Security fixes:
- Fix XSS in Atom feed: escape user-supplied URLs in HTML content
- Wrap signup request approval in a transaction to prevent
partial state on crash (user created but request still pending)
- Stop leaking internal error messages to admin UI
- Add request body size limit on API import endpoint
- Log SetMustResetPassword errors instead of silently discarding
Correctness fixes:
- Handle errors from API fave update/delete instead of returning
success on failure
- Use actual data timestamp for feed <updated> instead of
time.Now() (improves HTTP caching)
- Replace hardcoded 10000 export limit with named constant
(maxExportFaves = 100000)

Phase 5 — Feeds & Import/Export:
- Atom feeds: global (/feed.xml), per-user (/u/{name}/feed.xml),
per-tag (/tags/{name}/feed.xml). Uses gorilla/feeds.
- JSON export: all user's faves with tags, pretty-printed
- CSV export: standard format with header row
- JSON import: validates and creates faves with tags
- CSV import: flexible column mapping from header row
- Import/export pages with format documentation
- Feed items include enclosure for images, author info
- Limited-visibility profiles excluded from feeds
