my-sea spectator: render all present members on the hex (2C-6C), not just the viewer — TDD

The spectator hex showed only owner 1C + the viewer in 2C; other present
visitors were invisible. The view now builds a  list — owner 1C + each
present invitee in 2C-6C by deposit order (capped at MY_SEA_MAX_VISITORS) — so
every viewer sees the same absolute seating, with their own seat marked
.table-seat--self (a subtle --terUser tint).

- my_sea_visit:  context (present/empty + token + label + is_self).
- my_sea_visit.html: seat ring loops  instead of a hardcoded 1C/2C.
- _room.scss: .table-seat--self chair tint.
- +1 IT (3 present visitors → 2C-4C seated, viewer is the --self one); the
  both-seated IT updated for the --self marker. 292 gameboard ITs green.
