Implements createUser() endpoint to allow account creation via the
KOSync protocol. Changes default sync server from sync.koreader.rocks to
sync.crosspointreader.com with migration logic to preserve existing
users' server settings. Extends sync protocol to include position data
(spine index, page numbers, xpath) that crosspoint-sync supports while
remaining compatible with standard kosync servers.
## Summary
Make KOReader progress sync a one-click flow for common cases while
keeping the existing manual mode available.
### Changes
- Add a **Sync Behavior** setting:
- **Smart sync** for new configurations
- **Ask every time** for manual control
- Preserve **Ask every time** when migrating an existing credential file
that predates this setting.
- In Smart mode:
- upload local progress when no remote record exists;
- show a short confirmation when already synced;
- upload when local progress is further ahead;
- apply remote progress when remote progress is further ahead.
- Probe both KOReader document-matching hashes before making the Smart
decision, while keeping uploads on the user's configured matching
method.
- Auto-return after successful Smart terminal states, with Back/Confirm
still available.
- Persist the setting alongside the current credential, matching-method,
and send-metadata fields.
- Document both behaviors in the user guide.
## Additional context
This pairs well with #2189 (smart Wi-Fi auto-connect), but does not
depend on it. It does not add background Wi-Fi or passive network
detection; sync is still triggered by the user from the reader menu.
Smart sync uses the furthest progress because CrossPoint does not
currently persist local progress timestamps. Users who prefer explicit
conflict resolution can select **Ask every time**.
## Verification
- `git diff --check`
- `platformio check --fail-on-defect low --fail-on-defect medium
--fail-on-defect high` — no defects
- `platformio run -e default` — firmware build successful
- The original implementation was manually smoke-tested on an X4 device.

## Summary
- Hold the menu (Confirm) button for ≥1s while reading an EPUB to launch
the existing `KOReaderSyncActivity` directly — replaces the three-step
path (open reader menu → scroll to Sync → confirm) with a single
gesture.
- Reuses `ReaderUtils::GO_HOME_MS` (same 1s threshold used by long-press
Back) and the existing `KOREADER_STORE.hasCredentials()` guard.
- Adds a Controls picker **"Long-press Menu"** (`longPressMenuFunction`,
default **Bookmark**) that **cycles through the available functions**
bound to the long-press gesture: `KOSync → Disabled → Bookmark`. The
field name and `LONG_PRESS_MENU_FUNCTION` enum are intentionally general
so future actions (dictionary lookup, table of contents, etc.) can be
appended without another schema migration. The setting is **not** a
binary toggle.
- Existing menu Sync entry still works — both call sites share one
extracted helper (`launchKOReaderSync`); no logic duplication.
- Short-press Confirm release is gated on duration so the reader menu
does not also open after a long press that *acts*, mirroring the
existing long-press Back pattern.
- **No-credentials fall-through:** `launchKOReaderSync()` now returns
whether it acted. When the function is set to KOSync but no KOReader
credentials are stored, the long-press is a no-op that **falls through
to open the reader menu** — so the menu stays reachable instead of the
hold silently swallowing the gesture. The release is only suppressed
when sync actually launched or surfaced a save error.
## Test plan
- [x] `pio run` succeeds clean for the `default` ESP32-C3 environment.
- [x] On-device, value **KOSync**, valid KOReader credentials:
long-press Confirm ≥1s → sync screen launches; get + update progress
return HTTP 200; release does **not** also open the reader menu; returns
to the same page.
- [x] On-device, value **KOSync**, **no** credentials: long-press
Confirm falls through and **opens the reader menu** (regression fix);
short-press also opens the menu.
- [x] On-device: menu → Sync still launches the same screen (shared
helper) and syncs (200/200).
- [x] On-device, value **Bookmark**: long-press drops a bookmark and
does **not** also open the menu.
- [x] On-device, value **Disabled**: long-press Confirm opens the menu
on release; no sync, no bookmark.
- [x] On-device: long-press Back still goes to the file browser
(unchanged path).
- [x] Heap: epub is released before the TLS handshake (frees ~16 KB);
min free heap stayed ~84 KB during sync, well above the safe floor. No
panics/OOM across the session.

## Summary
* **What is the goal of this PR?** Update project documentation to match
the current master implementation for cache formats, i18n, file
transfer/web server workflows, SD-card fonts, and root user-facing docs.
* **What changes are included?** Refreshes `book.bin`/`section.bin` docs
for v6/v25, updates File Transfer/Calibre/WebDAV/API docs, documents 24
UI languages and JSON language persistence, updates root
README/USER_GUIDE cache and network details, and syncs the tracked
CLAUDE skill doc cache-version notes.
## Additional Context
* Docs-only change. Verified with `git diff --check origin/master..HEAD`
and stale-reference greps for old cache versions, removed i18n APIs, old
WiFi screen wording, and raw `Serial.printf` examples. No firmware build
was run.

## Summary
**What is the goal of this PR?**
Add Wi-Fi network management to the Web UI settings page, similar to
existing OPDS server management, so users can view, add, edit, and
delete saved Wi-Fi credentials from the browser. Closes
https://github.com/crosspoint-reader/crosspoint-reader/issues/1544 and
https://github.com/crosspoint-reader/crosspoint-reader/discussions/607
**What changes are included?**
- Added Wi-Fi API endpoints:
- GET /api/wifi Listing saved networks (without exposing plaintext
passwords)
- POST /api/wifi Creating/updating networks
- POST /api/wifi/delete Deleting networks by index
- Added a new Wi-Fi Networks management section web UI settings page

## Summary
* Add support for configuring and using multiple OPDS servers, replacing
the previous single-server limitation. Closes
https://github.com/crosspoint-reader/crosspoint-reader/issues/1178
* New OpdsServerStore singleton (modeled after WifiCredentialStore) that
persists up to 8 OPDS servers to /.crosspoint/opds.json with MAC-based
password obfuscation.
* One-time migration from legacy single-server fields in
CrossPointSettings to the new store on first boot.
* New OpdsServerListActivity for the device UI — works in two modes: a
settings list (add/edit/delete servers) and a picker (select which
server to browse). When only one server is configured, the picker is
skipped automatically.
* Renamed CalibreSettingsActivity → OpdsSettingsActivity for clarity. It
now edits individual OpdsServer entries (name, URL, username, password,
delete).
* OpdsBookBrowserActivity now receives an OpdsServer at construction and
uses its credentials for all fetches/downloads, and shows the server
name in the header.
* HttpDownloader::fetchUrl and downloadToFile accept optional per-call
username/password parameters instead of reading from global settings.
* REST API endpoints on CrossPointWebServer: GET /api/opds, POST
/api/opds, POST /api/opds/delete — passwords are never exposed over the
API (only a hasPassword flag), and omitting the password field on update
preserves the existing one.
* Web UI (SettingsPage.html) with dynamic OPDS server management cards —
add, edit, save, and delete servers from the browser.

/>
## Additional Context
* The OpdsServerStore JSON format and obfuscation scheme are identical
to WifiCredentialStore, so the same JsonSettingsIO infrastructure
handles both.
* The web API uses POST /api/opds/delete instead of DELETE /api/opds
because the ESP32 WebServer doesn't support the DELETE method with a
request body.
* Existing single-server configurations are migrated automatically — no
user action required. After migration the legacy CrossPointSettings
fields are cleared so it only runs once.
* The HttpDownloader changes are backward-compatible: the credential
parameters default to empty strings, so existing callers are unaffected.
