Notify updates for disabled installed apps

[anod]

After #167, updates for disabled/sleeping installed apps were silently consumed during sync, so users never got notified about new releases of apps their system put to sleep (#171). This keeps detecting and notifying those updates while the UI continues to show the app as "Installed but disabled" rather than updatable.

Approach

• Sync: disabled apps go through the normal decision path again. A new release persists STATUS_UPDATED and advances the cached versionNumber, so it is notified once and later syncs don't repeat it. The CLEAR_DISABLED_UPDATE / DISABLED_INSTALLED decisions are removed.
• UI unchanged in meaning: the Updatable filter, New/Recent sections, section ranking and details presentation already gate on isPackageEnabled, so disabled apps still show the disabled label and are not listed as updatable. Re-enabling the app reveals the existing update without a new notification.
• Notification payload: UpdatedApp gets an explicit installedEnabled (no default) and canUpdateOnDevice. The "Update" action is only offered when the app is installed and enabled.
• Removed clearing: disabled-status clearing on startup, at sync start and on package broadcasts is gone, along with the now-unused DAO queries.

Notes

• Releases already silently consumed under 1.7.2 are not retro-notified; the next sync restores their status silently.
• Release baseline profile files still reference removed methods; they are regenerated at release.

Tests

Updated/added cases in UpdateCheckVersionRollbackTest, SyncNotificationFilterTest, WatchListPagingSourceRoomTest and AppItemStateTest. Full :app:testDebugUnitTest and ktlintCheck pass.

Fixes #171
