Extends the async-witness WS so a visitor joining (deposit) or leaving (BYE)
pushes the seat ring to the other watchers — they see members come + go without
a refresh, same channel as the live draw.
- views.py: `_my_sea_seats(owner)` extracted (owner 1C + present invitees 2C-6C
by deposit order, sans per-viewer is_self) — used by BOTH the my_sea_visit
render (layers is_self on) AND a new guarded `_notify_sea_seats(owner_id)`
broadcast. Fired from my_sea_visit_insert_token (seat taken) +
my_sea_visit_leave (seat freed).
- consumers.py: MySeaSpectateConsumer gains a `sea_seats` handler.
- my_sea_visit.html: the WS client re-renders the `.table-seat` ring from a
`sea_seats` message, re-marking the viewer's own --self chair via the embedded
seat token + re-firing the one-shot seated glow (localStorage-gated).
Tests: +1 channels relay IT (sea_seats received) + 2 view ITs (deposit / BYE
each broadcast the ring). Existing multi-seat ITs stay green on the refactored
helper. Client re-render needs live 3-party verification on staging.
