GAME KIT: DON|DOFF equip system — portal tooltips, kit bag sync, btn-disabled fix

- DON/DOFF buttons on left edge of game kit applet portal tooltip (mirroring FLIP/FYI)
- equip-trinket/unequip-trinket/equip-deck/unequip-deck views + URLs
- Portal stays open after DON/DOFF; buttons swap state in-place (_setEquipState)
- _syncTokenButtons: updates all .tt DON/DOFF buttons after equip state change
- _syncKitBagDialog (DOFF): replaces card with grayed placeholder icon in-place
- _refreshKitDialog (DON): re-fetches kit content so newly-equipped card appears immediately
- kit-content-refreshed event: game-kit.js re-attaches card listeners after re-fetch
- Bounding box expanded 24px left so buttons at portal edge don't trigger close
- mini-portal pinned with right (not left) so text width changes grow/shrink leftward
- btn-disabled moved dead last in .btn block — wins by source order, no !important needed
- Kit bag panel: trinket + token sections always render (placeholder when empty)
- Backstage Pass in GameKitEquipTest setUp (is_staff, natural unequipped state)
- Portal padding 0.75rem / 1.5rem; tt-description/shoptalk smaller; tt-expiry --priRd
- Wallet tokens CSS hover rule for .tt removed (portal-only now)
