Show feedback in the admin panel and as aggregate stats on the briefing page

Feedback was only ever written to session_setting rows with no way to
view it short of querying the database directly. Adds a FeedbackService
that pulls per-player feedback entries and aggregate averages, backing
two new views:

- /admin/feedback: a full table of every submission (game, session,
  player, ratings, comment) plus summary tiles, linked from the admin
  sidebar.
- /briefing: a "Field Reports" block with the average difficulty/
  entertainment/theme ratings, shown to prospective players. Free-text
  comments are deliberately left off this public page since they're
  unmoderated player input.
