chore: cut v5.0.0 release (version bump)v5.0.0

Bumps the app to 5.0.0 now that all four v5.0.0 workstreams have landed:

- AppVersion.current 4.9.0 -> 5.0.0
- MARKETING_VERSION 4.9.0 -> 5.0.0 across all targets (app, widget, share
  extension, and both test bundles)
- CURRENT_PROJECT_VERSION 44 -> 45 across all targets
- RELEASE_ROADMAP.md: v5.0.0 marked shipped, "Current version" -> v5.0.0

The three version sources are kept in lockstep, matching the v4.4.1 alignment
policy. App Store archive/submit remains a manual step outside the repo.
