Server-side decoding makes client-side decoders redundant. Remove
~1000 lines of browser-side Bell 202 AFSK, AX.25/APRS parsing, and
Goertzel CW decoding. The frontend now relies solely on the /decode
SSE endpoint for decoded data.

Clears the packet list, map markers are unaffected. Also wipes
the persisted packet history from localStorage.

Add /decode SSE endpoint streaming decoded messages from the server.
Add decode channel OnceLock with set/subscribe pattern.
In the browser, connect to /decode EventSource and dispatch to
onServerAprs/onServerCw handlers. APRS and CW plugins now receive
server-decoded data automatically while keeping browser-side decoding
as a fallback.

Add localStorage persistence (trx_ prefix) for UI settings:
- Jog step, RX/TX volume (app.js)
- CW WPM, tone, threshold, auto-detect flags (cw.js)
- APRS decoded packets and running state (aprs.js)
APRS decoder auto-restarts on page refresh if it was active,
and all decoded packets plus map markers are restored from storage.

Render non-ASCII characters in decoded APRS info text as yellow
[0xNN] hex tags. Printable ASCII is HTML-escaped to prevent XSS.

Show the proper APRS symbol sprite icon on map markers instead of
generic green circles. Falls back to a green circle marker when no
symbol info is available.

Add a Map sub-tab under Plugins that displays an interactive
OpenStreetMap via Leaflet.js showing:
- Receiver location (blue marker) from server config lat/lon
- APRS station positions (green markers) updated in real-time
The map lazy-initializes on first tab switch, handles tile rendering
on tab visibility changes, and deduplicates station markers by
callsign. Also includes the fallback snapshot lat/lon fields in the
API layer.

- Add APRS symbol icons using hessu/aprs-symbols sprite sheets
- Parse uncompressed and compressed position formats for lat/lon
- Render clickable OpenStreetMap links for position packets
- Replace delay-and-multiply discriminator with mark/space correlation
detector for more robust AFSK decoding
- Reduce PLL gain from 0.7 to 0.4 for stable clock recovery
- Move plugin JS files to plugins/ subdirectory

Add Auto checkboxes (checked by default) next to WPM and Tone inputs.
Auto Tone uses a multi-bin Goertzel scan across 300-1200 Hz with
stability tracking. Auto WPM collects on-durations in a rolling buffer
and uses k-means-style clustering to separate dits from dahs.
Unchecking Auto allows manual control.
