Fix logical project grouping labels on mobile

[juliusmarminge]

Summary

• build the phone project filter from logical project scopes instead of raw project records
• show logical repository labels on Thread List V2 rows on phone and tablet
• use repository labels consistently for singleton repository scopes

Verification

• vp test run apps/mobile/src/features/home/homeThreadList.test.ts
• targeted vp lint --report-unused-disable-directives on changed files
• vp run --filter @t3tools/mobile typecheck
• vp run lint:mobile
• iOS Simulator against disposable state with two physical projects from one repository

Note

Low Risk
UI labeling and client-side list filtering only; no auth, API, or persistence changes.

Overview
Mobile home and sidebar thread lists now use logical project scope titles (e.g. repository display names) instead of raw per-environment project titles when repository grouping is enabled.

buildHomeProjectScopes and thread group building always call deriveProjectGroupLabel, so a single project in a repo scope shows the repository label rather than a local worktree name. Project filter chips and menus are built from those scopes via buildHomeProjectScopes, respecting grouping mode.

Selecting a scope filters threads and pending tasks across every projectRef in that scope (not a single raw project). Thread List V2 rows receive an optional projectTitle so favicons and row text match the scope label on phone and tablet.

The thread-list filter menu no longer includes a Settings action (settings remain on the header); tests assert that removal.

Note

Fix project grouping labels on mobile home screen to use repository display names

• Updates buildHomeProjectScopes and buildHomeThreadGroups in homeThreadList.ts to always derive scope/group titles via deriveProjectGroupLabel, even for single-project scopes, so repository display names appear instead of raw project titles.
• Updates HomeScreen and ThreadNavigationSidebarPane to map project keys to scope-level titles and pass them to ThreadListV2Row, which now accepts an optional projectTitle prop with fallback to project.title.
• Replaces per-project filter entries in HomeRouteScreen with buildHomeProjectScopes, so the Project submenu reflects grouped scopes and reacts to projectGroupingMode.
• Removes the Settings action from the thread list options menu in home-list-filter-menu.ts and HomeHeader.
• Behavioral Change: project filter selection now scopes threads and pending tasks across multiple projects within a grouped scope.
