Subject: [PATCH] Fix session UNIQUE constraint race, fix table horizontal
 scrollbar
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- create_session uses INSERT OR IGNORE to handle concurrent requests
  with same session cookie (race when multiple requests arrive before
  the first INSERT commits)
- Widen actions column 110px→130px to fit 3 action buttons without
  overflowing (was causing 4px horizontal scrollbar)
- Widen status column 100px→120px for DOWNLOADING badge breathing room
