Add Pubky profile, contacts, and Ring auth import flow

- Profile creation with restore flow (detects existing remote profile)
- Ring auth flow with contact import overview and selection screens
- Pay Contacts onboarding step after profile creation and Ring import
- Session restoration with re-sign-in recovery, preserving session on failure
- Toast notification when session restoration fails
- Lightbulb icon and tag suggestion button placement fixes
- Edit profile error message fix
- PubkyProfileData backward-compatible decoding (tags field defaults to [])
- New tests for PubkyProfileData encoding/decoding

    - Async operations should delegate to `@Observable` business logic objects
 
 4. **Component Design**
+   - **Always reuse existing components** before creating new ones — check `Components/` for buttons, text styles, layouts, and other shared UI. If identical or near-identical UI exists elsewhere in the codebase, extract it into a shared component rather than duplicating it.
+   - Use the project's text components (`DisplayText`, `HeadlineText`, `TitleText`, `SubtitleText`, `BodyMText`, `BodyMSBText`, `BodySSBText`, `BodySText`, `CaptionMText`, `CaptionText`) instead of raw `Text().font().foregroundColor()` chains.
    - Decompose views into small, focused, single-purpose components
    - Use descriptive names (e.g., `UserProfileCard` not `Card`)
    - Prefer composition over deep view hierarchies
