P0.2: migrate screens to LocalDataManager.current

Swaps direct `DataManager.xxx` access for `LocalDataManager.current.xxx`
across every Compose screen under ui/screens/** that references the
singleton. Each composable resolves the ambient once at the top of its
body and reuses the local val for subsequent reads — keeping rewrites
minimal and predictable.

Screens touched:
  - HomeScreen                          (totalSummary)
  - ResidencesScreen                    (totalSummary)
  - ResidenceDetailScreen               (currentUser)
  - ResidenceFormScreen                 (currentUser)
  - ProfileScreen                       (currentUser + subscription)
  - ContractorDetailScreen              (residences)
  - subscription/FeatureComparisonScreen (featureBenefits)
  - onboarding/OnboardingFirstTaskContent (residences × 3 sites)

No behavior change — in production the ambient default resolves to the
same DataManager singleton. The change is purely so tests, previews, and
the parity-gallery can `CompositionLocalProvider(LocalDataManager provides fake)`
to substitute a fake without tearing screens apart.

Files under ui/subscription/** and ui/components/AddTaskDialog.kt also
reference DataManager but live outside ui/screens/** (plan's scope) —
flagged for a follow-up pass.
