Move persistent history from trx-client to trx-server where decode
events originate. History for AIS, VDES, APRS, CW, FT8, and WSPR is
loaded from ~/.local/cache/trx-rs/history.db at startup and flushed
to disk every 60 seconds. CW events are now also stored in
DecoderHistories and replayed to connecting clients, consistent with
all other decoder types.

Add pickledb-backed persistent history store for all decoder types
(AIS, VDES, APRS, CW, FT8, WSPR). History is loaded from
~/.local/cache/trx-rs/history.db at startup and flushed to disk
every 60 seconds. On load, entry timestamps are reconstructed from
stored Unix ms values so 24h pruning continues to work correctly.

Two problems prevented reliable recovery after a persistent overflow:
1. Restart storm: once read_error_streak >= 3, every subsequent read
failure triggered a deactivate/activate cycle, potentially preventing
the hardware from stabilising. Fix: after a successful restart, reset
read_error_streak to 1 so the stream gets 2 more failures before the
next restart attempt.
2. Stuck-deactivated stream: if activate() failed after overflow, the
stream was left deactivated. Subsequent reads returned non-overflow
errors which handle_read_error ignored (Ok(false)), so the stream was
never reactivated. Fix: add a high-streak fallback (>= 10 consecutive
errors of any kind) that also attempts a full deactivate/activate
restart, covering the stuck-deactivated case.

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.

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.

- Reduce analysis window from 50ms to 10ms so the decoder can detect
dits at 25+ WPM (at 25 WPM a dit is 48ms, shorter than the old window)
- Fix dot/dash classification threshold from 2.0× to 1.5× unit_ms;
ITU Morse dah = 3× dit, so the midpoint boundary is 1.5×
- Replace O(n) on_durations.remove(0) with drain() to trim the window
- Remove pointless emit_text() wrapper; callers now call emit_event()
directly
