fix: Mastodon API status creation — links, CW, timeline timing

- Provide content as {text, html} with linkified URLs (Micropub's
  markdown-it doesn't have linkify enabled)
- Use content-warning field (not summary) to match native reader and
  AP syndicator expectations
- Remove premature addTimelineItem — post appears in timeline after
  syndication round-trip, not immediately
- Remove processStatusContent (unused after addTimelineItem removal)
- Remove addTimelineItem import

lib/mastodon/routes/statuses.js
