First round of testing feedback: images, unread landing, dark, delete

- Fix OPML import status message reporting the raw pre-dedup count
  (144) instead of the actual unique feed count after Room's upsert
  collapses duplicates (108) -- cosmetic bug, the DB was already
  correct.
- Article thumbnails: extract media:thumbnail/enclosure or the first
  <img> in feed content, show via Coil in the article list.
- App now lands on Unread instead of the feed list; a top-bar icon
  gets from there to the feed list (forward nav, not back-stack pop,
  since Unread is now the root).
- Dark color scheme by default.
- Delete-feed action (with confirmation) on each feed row -- was
  entirely missing. Deletes its non-saved articles too, so they don't
  linger as orphaned rows in the cross-feed Unread view; saved articles
  are kept regardless.
- Room migration 1->2 for the new imageUrl column (real migration, not
  destructive fallback, since there's now real on-device subscription
  data from testing).
