feat(widget): per-residence widget configuration (Android, gitea#6)

Mirrors the iOS implementation. Adds a Glance configuration activity
that launches when the user pins a new honeyDue widget tile and again
on "Edit Widget", lets them pick one of their residences (or "All
residences"), and persists the choice per-`appWidgetId`. Each tile's
`provideGlance` resolves its own scope and filters tasks (and stats,
on the large widget) accordingly.

Pieces:

- `WidgetConfigActivity` — Compose `ComponentActivity` hosting the
  residence-picker UI; reads the persisted residences sidecar, reads
  any prior scope for the current `appWidgetId`, writes the new
  selection on Save, and re-renders every widget tile.
- `WidgetDataStore` — new `widget_residences_json` key + a per-instance
  `widget_residence_id_<appWidgetId>` key. `clearAll()` sweeps the
  per-instance keys by prefix so logout doesn't leave dangling state.
- `WidgetDataRepository`:
  * `saveResidences(_)` / `loadResidences()` for the picker.
  * `saveResidenceIdFor(appWidgetId, residenceId)` /
    `loadResidenceIdFor(appWidgetId)` /
    `clearResidenceIdFor(appWidgetId)` for per-tile scope.
  * `loadTasksForResidence(residenceId)` and the
    `appWidgetId`-driven `loadTasksForWidget(appWidgetId)`.
  * `computeStatsFromTasks(tasks)` so the large widget's tiles
    reflect only the scoped task list (instead of the whole cache).
  * Pure `Filter.filterTasksForResidence(_, _)` on the companion
    object — easy to exercise from unit tests.
- `WidgetTaskDto` already carries `residenceId`. New `WidgetResidenceDto`
  added (id + name) — JSON-persisted via the sidecar.
- `WidgetRefreshWorker` / `DefaultWidgetRefreshDataSource` — pull
  `myResidences` alongside tasks/tier on each refresh and write the
  sidecar (best-effort; non-fatal if the call fails).
- `HoneyDue{Small,Medium,Large}Widget.provideGlance` — resolve
  `appWidgetId` via `GlanceAppWidgetManager(context).getAppWidgetId(id)`
  and call `loadTasksForWidget(appWidgetId)`.
- `HoneyDue{Small,Medium,Large}WidgetReceiver.onDeleted` — purge the
  per-instance residence scope key when the tile is removed.
- Manifest: register the configure activity with the
  `APPWIDGET_CONFIGURE` action.
- `honeydue_{small,medium,large}_widget_info.xml` — declare
  `android:configure="com.tt.honeyDue.widget.WidgetConfigActivity"`.

Migration / safety:
- A tile that's never been through the picker has no residence id
  saved → `loadTasksForWidget` returns every task (legacy "All
  residences" behaviour). Existing tiles keep working without the
  user touching anything.
- The picker handles an empty residences list (signed-out / first
  install before background refresh) with an explicit helper message
  pointing at the main app.

Tests: new `WidgetResidenceFilterTest` (commonTest-style under
`androidUnitTest`, 9 cases). All green.
