Add NIP-05 badges, hashtag pages, keyword muting, suggestion dismissal, notification poller

- Article cover: aspect-video replaces max-h-72 for consistent 16:9
- NIP-05 verification badge on note cards with 1-hour TTL cache
- Dedicated hashtag feed pages (clicking #tag opens live feed, not search)
- Keyword muting: word-boundary matching, applied across all feed views
- Follow suggestion dismissal: persistent "don't suggest again" per person
- Background notification poller (60s): mentions, zaps, new followers
- All notification types independently toggleable in settings
- Centralized notification firing (removed inline store notifications)
