Improve searchable filters and responsive calendar entries

[AKolenda]

Summary

Improves calendar readability and the high-volume project/client/tag selection workflows across Track and Statistics.

• split project and task search into clearer, independently searchable pickers
• preserve or optionally clear tracking fields after stopping an entry
• make project selection adaptive and searchable instead of an overflowing modal/menu
• collapse secondary Track search controls behind an advanced-options affordance
• collapse Statistics date presets into a range selector and add project search to filters
• let week-calendar metadata wrap through all available event-card height before clipping
• improve foreground sync-operation timing coverage and responsive screenshot fixtures

Scope and acceptance criteria

• Long project, client, task, and tag catalogues are searchable without unbounded menus.
• Track search remains immediately usable while secondary options stay collapsed.
• Statistics date and project filtering remains compact and searchable.
• Week-view cards use available horizontal and vertical space before clipping metadata.
• Tracking field retention behavior is explicit, persisted, and tested.
• English, Dutch, and Japanese resources remain aligned.

Validation

Commands and focused tests actually run:

./gradlew.bat --no-daemon spotlessApply -> passed
./gradlew.bat --no-daemon spotlessCheck testDebugUnitTest :app:recordRoborazziDebug -> passed
./gradlew.bat --no-daemon spotlessCheck testDebugUnitTest lintDebug assembleDebug assembleDebugAndroidTest :app:assembleBenchmark -> passed (159 tasks)
apksigner verify --verbose app/build/outputs/apk/benchmark/app-benchmark.apk -> passed (APK Signature Scheme v2)
git diff --check -> passed

Verification status by scope:

• Host/unit/lint: Green — formatting, complete debug unit suite, lint, debug APK, and test APK passed.
• Screenshot/UI: Green — Roborazzi recording passed; intentional calendar and responsive UI fixtures were reviewed.
• Device/E2E: Partial — instrumentation APK compiled; no physical-device instrumentation run was performed.
• Backend/server evidence: Not applicable — this is local UI/preference behavior and no production or live backend was contacted.

Evidence and remaining gaps

• Focused Compose coverage includes large searchable catalogues, project/task interactions, statistics filtering, tracking retention, and foreground timing.
• The optimized benchmark APK was built with R8/resource shrinking and its signature verified.
• Remaining gap: physical-device interaction and accessibility verification were not run.

Safety and working tree

• No tokens, work data, or machine-specific paths are included.
• Unrelated changes were preserved.
• Generated artifacts are intentional and reviewed.

Superseded by a clean replacement PR that includes deterministic ViewModel-scope teardown and updates the affected picker, notification, and sync E2E fixtures based on the failed CI run.
