When the user changes frequency, applyLocalTunedFrequency sets lastFreqHz
optimistically. But the SSE state stream could push back the old server
frequency before set_freq completes, causing the marker to snap back then
forward. Add a sequence-guarded _freqOptimisticHz that suppresses stale
SSE frequency updates while a set_freq is in flight.

Replace synchronous drawSignalOverlay() calls in freq/BW change handlers
with lightweight CSS div elements repositioned via transform: translateX().
This is GPU-composited with zero layout/paint cost, making frequency and
bandwidth changes appear instantaneous. The full WebGL overlay catches up
on the next requestAnimationFrame.

Selected rig mirrors to global channels for backward compat. Also fix bookmark apply to update spectrum marker instantly and fire all requests in parallel.

When ?rig_id= is specified on /audio, don't fall back to the global broadcast (which carries whichever rig is connected). Return 404 for rigs without an active audio connection instead of silently delivering the wrong rig's audio. Also create per-rig audio channels for all known rigs eagerly so connected rigs are instantly subscribable.

Each browser tab can now subscribe to a specific rig's spectrum and
audio independently via ?rig_id= query params on /spectrum and /audio.
The remote client polls spectrum for all rigs with active subscribers
and routes responses to per-rig watch channels. Virtual channel
commands are routed through per-rig senders with global fallback.

When a new tab connects and receives the initial channels event,
automatically subscribe to channel 0 (primary) so the session joins
the same tuned channel as other users on that rig. Uses a lightweight
auto-join that skips scheduler control takeover since audio isn't
started yet at this point.

select_rig no longer mutates remote_active_rig_id — only the per-session
mapping is updated. This eliminates cross-tab leaking entirely: each tab
carries its own rig_id via the session manager, /events?rig_id, and
/status?rig_id query params.
The global remote_active_rig_id now only serves as the startup default
for brand-new sessions that have no rig_id yet.
Also fix the About section to show the per-tab lastActiveRigId instead
of the server's global active_rig_id.

pollFreshSnapshot() fetches GET /status on every SSE connect/reconnect,
but /status always returned the global selected rig's state, overwriting
the per-tab display with whichever rig was last switched to globally.
Now pollFreshSnapshot passes rig_id as a query param and the /status
endpoint uses the per-rig watch channel when provided, matching the
/events behavior for true per-tab rig isolation.

The previous commit conditionally skipped updating remote_active_rig_id
when session_id was provided, but the remote client reads the global to
route commands to the correct rig on trx-server. Restore the
unconditional global update; cross-tab SSE isolation is handled by the
rig_id query param on /events and the JS-side guard in applyRigList.

After select_rig stopped mutating the global remote_active_rig_id for
session-aware clients, SSE reconnects would fall back to the old global
default instead of the newly selected rig. Now connect() passes
lastActiveRigId as a rig_id query param to /events, and the server
prefers it over the global default when present.

add() and lookup() had no wrap-around guard in their linear-probe loops.
Once 256 unique callsigns filled the table, any subsequent add or lookup
for an absent hash would cycle through all 256 slots forever, hanging the
FT8 decoder task permanently inside block_in_place. On a busy band this
could happen within a few minutes of operation.
- add(): evict the probe-start slot when a full cycle completes
- lookup(): return None after a full probe cycle
- reset(): call cleanup(10) each slot boundary to age out stale entries
- Add regression tests for both infinite-loop scenarios
Also includes cargo fmt reformatting of pre-existing style issues.
