FN-5894: share project data-boundary and status helpers

Centralize project loading and status-state handling across dashboard surfaces.

- add a reusable DataBoundary component for loading, empty, error, and loaded states
- extract shared project status config helpers for labels, colors, icons, and initializing detection
- update project overview, cards, badges, and selector UI to use the shared helpers
- add regression coverage for data-boundary behavior, project overview empty/loading transitions, and status config fallbacks
