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.

The .audio-active state was using --accent-green which is actually

select_rig was unconditionally updating the global remote_active_rig_id,
causing all SSE sessions to see the changed rig. Now only the per-session
mapping is updated when session_id is provided; the global default is
only changed for non-session-aware clients.

Bump selector specificity to .header-bar-btn.header-audio-btn so the
padding: 0 rule wins over the generic .header-bar-btn padding, and
switch the SVG to width/height: 100% so it expands to fill the button.

Add per-rig watch::Sender<RigState> map to FrontendRuntimeContext,
populated by refresh_remote_snapshot for every rig returned by GetRigs.
The SSE /events endpoint now subscribes to the session's rig-specific
watch channel instead of the single global one, allowing different
browser tabs to independently view different rigs. The JS frontend
reconnects SSE on rig switch to pick up the new channel.

Add SessionRigManager to track per-SSE-session rig_id so different
browser tabs can independently select rigs without interfering.
The /events SSE stream filters state updates by session rig (falling
back to the global active rig), and /select_rig accepts an optional
session_id to update the per-session mapping.

The /select_rig endpoint sets global server state which affects all tabs. Since postPath() already sends rig_id with every command, the rig picker now just sets the local lastActiveRigId variable.

When specific SoapySDR device args are provided (e.g. with a serial number),
fail hard instead of silently falling back to Device::new("") which opens
the first available device. This caused multi-device setups to bind both
rig instances to the same physical device.

- Gate encode174_to_bits with #[cfg(test)] (only used in tests)
- Convert 40+ C-style index loops to idiomatic iterators

Eliminate duplicated code between FT2 and FT8/shared modules:

- Share pack_bits() from decode.rs, remove pack_bits91() from osd.rs
- Add verify_crc_and_build_message() to decode.rs, used by both FT8 and FT2
- Add normalize_llr() to decode.rs, replacing per-module normalization
- Make encode174() pub(crate), add encode174_to_bits() for bit-array output
- Wire FT2 decode_hit to use full BP+OSD decoder from osd.rs instead of
separate BP + sum-product + OSD-lite flow
- Align LLR scale factor to 2.83 matching reference implementation

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.
