add Carte Blanche trinket: equip system, gatekeeper multi-slot, mini tooltip portal; new token type Token.CARTE ('carte') with fa-money-check icon; migrations 0010-0012:

CARTE type, User.equipped_trinket FK, Token.slots_claimed field; post_save signal sets
equipped_trinket=COIN for new users, PASS for staff; kit bag now shows only the equipped
trinket in Trinkets section; Game Kit applet mini tooltip portal shows Equipped or Equip
Trinket per token; AJAX POST equip-trinket id updates equippedId in-place; equip btn
now works for COIN, PASS, and CARTE (data-token-id added to all three); Gatekeeper CARTE
flow: drop_token sets current_room (no slot reserved); each empty slot up to
slots_claimed+1 gets a drop-token-btn; slots_claimed high-water mark advances on fill,
never decrements; highest CARTE-filled slot gets NVM (release_slot); token_return_btn
resets current_room + slots_claimed + un-fills all CARTE slots; gate_status always returns
full template so launch-game-btn persists via HTMX when gate_status == OPEN; room.html
includes gatekeeper when GATHERING or OPEN; new FT test_trinket_carte_blanche.py (2
tests, both passing); 299 tests green
