Two bugs triggered by a SoapySDR IQ overflow:
1. Spectrum dies permanently (trx-client): when GetSpectrum times out
(300ms SPECTRUM_IO_TIMEOUT), the error was silently swallowed and
the spectrum buffer cleared. The in-flight response remained in the
TCP receive buffer, desynchronising all subsequent reads so every
poll kept failing. Fix: propagate the error so handle_connection
returns and the outer loop reconnects, restoring TCP sync.
2. CTRL+C hangs trx-server: after IQ overflow, the sdr-iq-read thread
can get stuck in a blocking SoapySDR/USB call (deactivate/activate
with no timeout). Tokio received SIGINT and aborted async tasks, but
the process could not exit while the native thread was blocked in
uninterruptible I/O. Fix: call std::process::exit(0) after the
graceful shutdown sequence so the OS forcibly terminates all threads.

Server emits an SSE sentinel event (history_done) after replaying
stored history. Client buffers all incoming messages until the sentinel
arrives, then drains the buffer in 30-event chunks via setTimeout so
the browser can handle input between batches. Live events after the
sentinel are dispatched immediately as before.

Prepend the in-progress line to the bar render so characters appear
immediately rather than waiting for a newline or 5s gap.

Show a live decode bar on the overview strip when in CW/CWR mode,
matching the APRS and AIS bar pattern. Accumulates decoded characters
into lines (split on newline events or >5s gaps), keeps a 15-minute
rolling history, and shows up to 8 recent lines with timestamp and
WPM/tone metadata. Clears on resetCwHistoryView.

Add cwAutoLocalOverride flag in cw.js to block server-state snapshots
from overriding the checkbox while a user-initiated POST is in-flight.
Expose applyCwAutoUiFromServer for app.js render() to call instead of
applyCwAutoUi, preventing a racing SSE event carrying the old cw_auto
value from immediately undoing the user's toggle.

Fix CW picker redraw when the decoder sub-tab becomes visible to avoid
