New game_admin_game_new route/form (reuses AdminGameType, same pattern
as editing a game's total time) so games - including the 3 upcoming
Easy/Medium/Hard difficulty options - can be created through the admin
panel instead of needing a direct DB insert.
Also show each game's total time (in minutes) next to the player
count in the "Create New Session" dropdown, since that's the actual
difficulty signal players are choosing between - number of players
alone didn't convey it.
Difficulty itself needs no new session-level concept: each difficulty
is just a separate Game row with its own TOTAL_TIME setting, which
checkAllPlayersReady() already reads when starting the session's
timer. Hint timing depending on difficulty is separate, upcoming work.
