Phase 1 of the room GATE VIEW + seat-renewal sprint. Decouples 1C
seating from hand/deposit/paid state: the owner is seated as long as
`active_draw_for` returns a row, i.e. for the full 24h after her most
recent FREE or PAID draw (PAID DRAW resets created_at, so the window
runs from the later of the two). A DEL'd row (empty hand, no paid
credit) now keeps 1C seated until the row expires at 24h — previously
1C dropped to .fa-ban the instant she DEL'd, even mid-window.
- `_my_sea_seats` `owner_seated` → `owner_draw is not None` (drives the
owner's own landing hex + the live `sea_seats` broadcast).
- `my_sea_visit` `owner_seated` → same rule, so the spectator hex and
the owner's landing agree (was drawn-OR-paid, dropped `owner_paid`).
- DRY: removed the dead `seat1_seated` context (the `seats` ring's
`seat.present` has driven 1C since the multi-seat hex landed; the flag
was never read by the template).
Tests — TDD red→green:
- flipped `test_seat_1c_not_seated_at_gate_view_after_del` →
`..._seated_...`: DEL'd empty-hand row keeps 1C seated, center still
GATE VIEW (1 check / 5 ban).
- flipped FT `test_seat_1_banned_when_active_draw_has_empty_hand` →
`..._seated_...` (asserts .fa-circle-check).
- added `test_seat1_seated_context_key_removed` (DRY regression guard).
- added spectator `test_owner_seated_with_empty_hand_no_payment`.
- `test_owner_not_seated_without_draw_or_payment` unchanged (no row →
still unseated). 318 gameboard ITs green.
