chore(deps): update gradle to v9.6.1

Release branch for 2.19.1. Merging this cuts the release — versionName is bumped to 2.19.1 (versionCode 21901), which is what release.yaml picks up.

### What's in it

- **Drag to reschedule can be turned off** (#173). Settings → Views → *Drag to reschedule*, on by default. Turned off, no event block in the month, week or day view registers a drag gesture. The gate is `EventMoveScope.dragEnabled` rather than the scope itself, so the screen-reader "Move event" action — which only opens the edit form — stays available either way. The setting reads as off until the stored value has actually loaded, so a cold start can't hand out a drag before the preference is known.

### Release prep

- CHANGELOG 2.19.1 section written.
- Per-version "What's New" hand-written for all 12 store locales (`ar`, `de-DE`, `en-GB`, `en-US`, `es-ES`, `fr-FR`, `it-IT`, `pl-PL`, `pt-BR`, `pt-PT`, `ru-RU`, `zh-CN`).
- `lint test assembleDebug` and `check_translations.py` green locally.
- main is one commit ahead (Weblate #175, translations only) and merges clean — not merged into the branch, it comes along with this one.

Closes #173
