[UI] Resident Documents screen and bottom navigation (Phase 9)

[CRamsan]

Phase 9 — Resident Documents and Navigation

Implement the resident-facing documents screen and the Resident bottom navigation bar. This is split from #408 which covers the entire Resident Experience.

Screens & Composables

MyDocumentsScreen.kt (RES-12)

• Thin wrapper around DocumentLibraryScreen ([UI] Document Library + Viewer + Upload screens (Phase 8) #407) with unitId fixed to resident's unit
• Upload FAB hidden (read-only for residents)
• Tapping a document navigates to DocumentViewerScreen
• Read-only: no upload, delete, or move capability

Resident Bottom Navigation (RES-14)

• Separate composable from Admin/Staff bottom nav
• Items: [Home | Requests | Documents | Profile]
• Displayed in the Resident NavHost scaffold
• Highlights active tab using Material3 NavigationBar active indicator

ViewModel

MyDocumentsViewModel.kt (RES-13): resolves resident's unitId via unit_occupants, calls DocumentManager.getDocumentsForUnit(unitId)

Navigation

• Route.MyDocuments, Route.ResidentProfile registered in Resident NavGraph
• Route.DocumentViewer shared with Admin/Staff graph or declared global

Dependencies

• [UI] Resident experience — role-based navigation and home screen (Phase 9) #408 — Resident NavGraph host (MyDocumentsScreen is a tab in Resident bottom nav)
• [UI] Document Library + Viewer + Upload screens (Phase 8) #407 — DocumentLibraryScreen and DocumentManager
