chore: Resolve static analysis warnings and reduce detekt baseline suppressions

[shobhitagarwal1612]

This PR addresses several static analysis findings identified by Android Lint, Detekt, and the Kotlin compiler, tunes analyzer configurations for tests, and significantly reduces suppressions in baseline.xml (from 8 down to 2).

All changes are non-breaking, verified with ./gradlew checkCode, and accompanied by passing unit tests across all modules.

Key Changes

• Compiler & Lint:
  • Adopted Android KTX extensions (toColorInt, toUri, bitmap[x, y]).
  • Fixed accessibility (android:focusable="true") and layout performance (android:baselineAligned="false").
  • Updated deprecated hiltViewModel Compose import and removed redundant Elvis operator.
  • Replaced unmanaged SavedStateHandle instantiation in HomeScreenViewModel with a plain property.
  • Stubbed default remoteConfig.getString(...) in TestFirebaseModule to match Firebase contracts.
• Detekt Baseline Reduction (8 $\to$ 2):
  • Eliminated labeled returns (@getMapAsync, @withReady) in GoogleMapsFragment and DataCollectionViewModel.
  • Simplified getDraftSubmission() in HomeScreenViewModel and reduced nesting depth in SubmissionDataConverter.
  • Removed obsolete DataCollectionTaskFragment suppression.
• Configuration:
  • Excluded test source sets from Detekt's LargeClass rule (removing DataCollectionFragmentTest from baseline).
  • Documented rationale for display_700.xml lint exclusion.
