1. Refactor Bitmap.cpp/h to expose the options for FloydSteinberg and
brightness/gamma correction at runtime
2. Fine-tune the thresholds for Floyd Steiberg and simple quantization
to better match the display's colors
Turns out that 2 is enough to make the images render properly, so the
brightness boost and gamma adjustment doesn't seem necessary currently
(at least for my test image).
## Summary
* **What is the goal of this PR?**
Fixes the Wi-Fi connection issue when launching the Calibre Library
(OPDS browser). The previous implementation always attempted to connect
using the first saved WiFi credential, which caused connection failures
when users were in locations where only other saved networks (not the
first one) were available. Now, the activity launches a WiFi selection
screen allowing users to choose from available networks.
* **What changes are included?**
## Additional Context
**Bug Fixed**: Previously, the code used `credentials[0]` (always the
first saved WiFi), so users in areas with only their secondary/tertiary
saved networks available could never connect.

## Summary
* **What is the goal of this PR?**
* This PR adds a setting to (additionally) map the forward page turn
onto the powerbutton when in `EPUBReaderActivity` and powerbutton short
press is not mapped to sleep mode. I find the powerbutton to be exactly
where my thumb is while reading so it is very convenient to map the
forwardpage turn to that. Maybe Im not alone with this ^^

## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks, specific areas to
focus on).
## Summary
* Remove HTML entity parsing
* This has been completely useless since the introduction of expat
* expat tries to parse all entities in the document, but only knows of
HTML ones
* Parsing will never end with HTML entities in the text, so the
additional step to parse them that we had went completely unused
* We should figure out the best way to parse that content in the future,
but for now remove that module as it generates a lot of heap allocations
with its map and strings
## Summary
Fixes https://github.com/daveallie/crosspoint-reader/issues/233
## Additional Context
By disabling the Text Anti-Aliasing in the settings, you can get faster
black-and-white page turns that work exactly like the stock firmware,
instead of having an additional flash after rendering (see issue linked
above for example).
Tested on the X4 and confirmed working.

## Summary
Adds feature to file selection activity for better user navigation when
ascending folders. The activity now remembers the index of the parent
folder instead of always resetting to the first element.
I don't have any means of testing this, so if someone could test it
that'd be great
Resolves#259
## Summary
Adds support for browsing and downloading books from a Calibre-web
server via OPDS.
How it works
1. Configure server URL in Settings → Calibre Web URL (e.g.,
https://myserver.com:port I use Cloudflare tunnel to make my server
accessible anywhere fwiw)
2. "Calibre Library" will now show on the the home screen
3. Browse the catalog - navigate through categories like "By Newest",
"By Author", "By Series", etc.
4. Download books - select a book and press Confirm to download the EPUB
to your device
Navigation
- Up/Down - Move through entries
- Confirm - Open folder or download book
- Back - Go to parent catalog, or exit to home if at root
- Navigation entries show with > prefix, books show title and author
- Button hints update dynamically ("Open" for folders, "Download" for
books)
Technical details
- Fetches OPDS catalog from {server_url}/opds
- Parses both navigation feeds (catalog links) and acquisition feeds
(downloadable books)
- Maintains navigation history stack for back navigation
- Handles absolute paths in OPDS links correctly (e.g.,
/books/opds/navcatalog/...)
- Downloads EPUBs directly to the SD card root
Note
The server URL should be typed to include https:// if the server
requires it - HTTP→HTTPS redirects may cause SSL errors on ESP32.
## Additional Context
* I also changed the home titles to use uppercase for each word and
added a setting to change the size of the side margins

Added a setting to select `fit` or `crop` for cover image on sleep
screen.
Might add a `expand` feature in the future that does not crop but rather
fills the blank space with a mirror of the image.

## Summary
* **What is the goal of this PR?**
* This PR adds a setting to control the top left and right margins of
the reader screen in 4 sizes (5, 10, 20, 40 pt?) and defaults to `SMALL`
which is equivalent to the fixed margin of 5 that was already in use
before.
* **What changes are included?**
## Additional Context
* Add any other information that might be helpful for the reviewer
(e.g., performance implications, potential risks, specific areas to
focus on).

## Summary
Fixes a bug in the settings menu, where previously wrap-around only
worked when scrolling upwards. Now, scrolling downwards on the last list
element wraps around to the top as expected.
Resolves#236.
