Merge https://github.com/google/adk-python/pull/1959
### What
Fix misleading comment.
```diff
- # Make sure a malicious user can obtain a session and events not belonging to them
+ # Make sure a malicious user **cannot** obtain a session or events not belonging to them
```
### Why
The previous wording contradicted the assertion `assert len(session_mismatch.events) == 0`, which verifies that a malicious user **cannot** access another user’s session or events.
### Testing plan
Docs-only change.

When get session is being called on a session with more than 1 page of events (100+), the response of the subsequent listevents calls fails due to missing parsing logic. This change fixes the processing of the listevents responses.

We are using `func.now()` to set the `onupdate` time for db, when SQLAlchemy generates the SQL to build the database, it actually translates `func.now()` into `NOW()` or `CURRENT_TIMESTAMP`. The value it returns depends on the database server settings. For example, if the global/default timezone for a db is set to be UTC, the update time will be set to be a UCT time; if the global time zone for a db is set to be a local time zone (e.g. America/Los_Angeles), the update time will be a local time.
Normally, the best practice is to set database server to use UTC. Applications will convert it into different time zones as needed.
For SQLite, there is no way to config the default timezone, it will just treat it as UTC. But because it is a naive datetime (with no timezone info), python will assume it is a local time and then covert it into a UTC, which is why we see the bug (e.g. we create a session at 2025-06-17 12:49:33 local time, but when we read the session, its last update time is 2025-06-17 19:49:33 local time).
The solution is converting the native datatime to be timezone aware before `.timestamp()`.
The change in this CL only affects SQLite database.

When the user id contains special characters (i.e. an email), we have added in extra url parsing to address those characters. We have also added an if statement to use the correct url when there is no user_id supplied.

fix(DatabaseSessionService): Align event filtering and ordering logic
This commit addresses inconsistencies in how DatabaseSessionService
handles config.after_timestamp and config.num_recent_events
parameters, aligning its behavior with InMemorySessionService and
VertexAiSessionService.
Key changes:
- Made after_timestamp filtering inclusive
- Corrected num_recent_events behavior to fetch the N most recent events
- Refined timezone handling for after_timestamp
- Updated the unit test test_get_session_with_config to includeSessionServiceType.DATABASE, allowing verification of these fixes.
