feat: add thumbnail settings UI to admin settings page (#206)

Browse Source 
Add a new "Thumbnails" tab in the admin settings page allowing users to
configure thumbnail dimensions, quality, format, and fit mode from the UI.
Also fix backend route column name mismatch (key/value → setting_key/setting_value)
that caused a 500 error, and add a button to regenerate all thumbnails.
