- Fix 55 test failures caused by missing request contexts and incorrect
session_transaction() usage across 8 test files
- Fix ruff import sorting errors and unused imports
- Fix 122 type errors: rename method override parameters to match base
classes, add None guards for fetchone()/datetime, widen dict type
annotations, add type: ignore for SQLAlchemy stub limitations
- Add [tool.ty.rules] config to suppress unsupported-base warnings
- Fix _ variable shadowing gettext in wizard routes
- Add noqa: ARG002 for unused method arguments required by base class
Jellyfin and Emby collectors were recording RunTimeTicks (total file
runtime) as the session duration, causing severe overestimation when
users stopped partway through long titles.
- JellyfinCollector._emit_session_event: on session_end, use position_ms
(last known playback position) as duration_ms; fall back to
raw_duration_ms only when position_ms is unavailable or zero.
- EmbyCollector._emit_session_event: identical fix (shared API shape).
- JellyfinHistoricalImporter._process_item: for partially-watched items
(UserData.Played == false) use PlaybackPositionTicks; keep RunTimeTicks
only for fully-played items where position has already been reset.
- historical_duration_source metadata field now accurately reflects
which source was used (runtime_ticks, playback_position_ticks, or
runtime_ticks_fallback).
Plex was already correct via elapsed-time tracking in SessionManager.
- Moved utility functions for datetime parsing, tick conversion, and session building from `historical_data.py` to a new module `utils.py`.
- Deleted the `historical_data.py` file as its functionality is now encapsulated in the new utility module.
- Updated the `build_activity_session` function to utilize the new utility functions for improved readability and maintainability.
