role-select UX: tray timing delays, seat/circle state polish, 394 ITs green

- _animationPending set before fetch (not in .then()) — blocks WS turn advance during in-flight request
- _placeCardDelay (3s) + _postTrayDelay (3s) give gamer time to see each step; both zeroed by _testReset()
- .role-confirmed class: full-opacity chair after placeCard completes; server-rendered on reload
- Slot circles disappear in join order (slot 1 first) via count-based logic, not role-label matching
- data-active-slot on card-stack; handleTurnChanged writes it for selectRole() to read
- #id_tray_wrap not rendered during gate phase ({% if room.table_status %})
- Tray slide/arc-in slowed to 1s for diagnostics; wobble kept at 0.45s
- Obsolete test_roles_revealed_simultaneously FT removed; T8 tray FT uses ROLE_SELECT room
- Jasmine macrotask flush pattern: await new Promise(r => setTimeout(r, 0)) after fetch .then()
