The admin panel already checked CSRF tokens on destructive actions,
but the player-facing raw HTML forms (create/join/leave/start
session, toggle ready, lobby chat, feedback) had none - cookie
SameSite=Lax blunts classic cross-site auto-submit attacks but isn't
a substitute for real tokens. Adds matching csrf_token()/
isCsrfTokenValid() checks to all of them.
Also adds login_throttling (5 attempts/15 min) to stop unlimited
password guessing, and a per-user rate limiter (10/min) on the
invite-code join endpoint, since invite codes are only 32-bit and
had no protection against brute-forcing.

The chat used to disappear the moment a session left CREATED status.
Sessions now record a finishedAt timestamp when they're won or lost,
and the lobby (with chat) stays reachable via /game/{session} for an
hour afterward instead of immediately redirecting to the win/lose
feedback page. The lobby template shows a distinct "game finished"
header with a link to that feedback page during this window.

Players used to get bounced back to the dashboard when a session
wasn't full yet. Now they land on a lobby page showing who has
joined, and can chat with each other while waiting - messages are
broadcast live over the existing Mercure hub, and the session
auto-starts (and the lobby notifies everyone) once it fills up.
