chore: remove dead code — scheduler, linkedom, inline-form CSS

- Remove scheduler.ts + scheduler.test.ts (adaptive check removed earlier)
- Remove unused shouldCheckArticle import from feed-poller
- Remove linkedom dependency (replaced by JSDOM)
- Remove .inline-form CSS (nested forms replaced by fetch buttons)
