2.19.1 — drag to reschedule can be turned off (#176)

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

+### Added
+- **Drag to reschedule can be turned off.** Settings → Views → *Drag to
+  reschedule*, on by default. Off, no event can be picked up in the month, week
+  or day view — for anyone who kept moving appointments by accident while
+  scrolling ([#173]).
+- An early Brazilian Portuguese translation. Calendula has started speaking
+  Brazilian Portuguese, contributed as a community translation through
+  [Calendula's Weblate](https://weblate.dev.jeanlucmakiola.de/projects/calendula/).
+  About a third of the app is covered, so the rest still shows in English — you
+  can pick it under Settings → Language or in Android's per-app language
+  settings. Thanks to
+  [bkrz](https://weblate.dev.jeanlucmakiola.de/user/bkrz/) for getting it
+  started; help finishing it is very welcome.
+
+### Fixed
+- **The language picker forgot which language was picked.** Android hands the
+  applied language back with its script filled in — Simplified Chinese goes in
+  as `zh-CN` and comes out as `zh-Hans-CN` — so after a restart no entry in
+  Settings → Language showed as selected, and the row above it named the
+  language the long way round. Only languages that imply a script were
+  affected.
