Add a dedicated fediverse reader view with:
- Timeline view showing posts from followed accounts with threading,
content warnings, boosts, and media display
- Compose form with dual-path posting (quick AP reply + Micropub blog post)
- Native AP interactions (like, boost, reply, follow/unfollow)
- Notifications view for likes, boosts, follows, mentions, replies
- Moderation tools (mute/block actors, keyword filters)
- Remote actor profile pages with follow state
- Automatic timeline cleanup with configurable retention
- CSRF protection, XSS prevention, input validation throughout
Removes Microsub bridge dependency — AP content now lives in its own
MongoDB collections (ap_timeline, ap_notifications, ap_interactions,
ap_muted, ap_blocked).
Bumps version to 1.1.0.
