Cover all parse_multimon_output code paths:
- Alpha and Numeric content types across POCSAG baud rates
- Empty content and special characters (base64, punctuation)
- Catch-all pattern for non-standard content type labels
- Address-only (Tone) messages with trailing whitespace
- FLEX simple format and unrecognized input lines

Add dropout tolerance (2 blocks ~40ms) to bridge brief signal gaps that
caused the state machine to chop dahs into multiple dits. Also fix scope
SNR display to use actual noise_ref instead of noise_floor.

Full-stack meteor scatter monitoring mode that captures IQ data from
an RTL-SDR, computes FFT waterfall frames via WebSocket, and runs a
real-time detection engine to identify transient VHF reflections from
meteor ionization trails (e.g. GRAVES radar at 143.050 MHz).
Backend: MeteorDetector with EMA noise floor, SNR threshold state
machine (IDLE/DETECTING/ACTIVE/COOLDOWN), hysteresis, and CSV/JSON
export. WebSocket at /ws/meteor for binary waterfall frames, SSE at
/meteor/stream for detection events and stats.
Frontend: spectrum + waterfall + timeline canvases, event table with
SNR/duration/confidence, stats strip, turbo colour LUT. Uses shared
SDR device selection panel with conflict tracking.

Extends the rtl_tcp support (added in c1339b6 for APRS, Morse, DSC) to
the weather satellite mode. When a remote SDR host is provided, SatDump
uses --source rtltcp instead of --source rtlsdr, local device claiming
is skipped, and the frontend sends rtl_tcp params via getRemoteSDRConfig().
Closes#166

Re-implements envelope detection on top of the rewritten Morse decoder.
Addresses PR #160 review feedback:
- Rebase: rebuilt on current upstream/main (lifecycle state machine)
- Gap thresholds: 2.0/5.0 for envelope only; goertzel keeps 2.6/6.0
- Frequency validation: max_mhz=1766 for envelope, 30 for goertzel
- Tests: EnvelopeDetector unit tests + envelope-mode decoder test
- Envelope uses direct magnitude threshold (no SNR/noise ref)
- Goertzel path completely unchanged

The registry used plain int keys (device index), so HackRF at index 0
and RTL-SDR at index 0 would collide. Changed to composite string keys
("sdr_type:index") so each SDR type+index pair is tracked independently.
Updated all route callers, frontend device selectors, and session restore.

- Add third location fallback to utils/constants (London 51.5074/-0.1278)
so location always resolves even without GPS or env vars configured
- Remove min-height from sys-card to eliminate wasted space
- Switch System Info to vertical key-value layout filling the card
- Clean up OS string (strip glibc suffix), use locale date for boot time
- Bump info grid font size from 11px to 12px for readability

Replace broken app.gps_state lookup with utils.gps.get_current_position()
and return GPS metadata (fix quality, satellites, accuracy). Shrink location
card to single-column with 200px globe, move System Info into row 2.

Add SVG arc gauge, per-core CPU bars, temperature sparkline, network
interface monitoring with bandwidth deltas, disk I/O rates, 3D globe
with observer location, weather overlay, battery/fan/throttle support,
and process grid layout. New /system/location and /system/weather endpoints.

Real-time dashboard for host metrics (CPU, memory, disk, temperatures),
active decoder process status, and SDR device enumeration via SSE streaming.
Auto-connects when entering the mode with graceful psutil fallback.

The previous magnitude-based threshold couldn't distinguish CW tone from
AGC-amplified inter-element silence — the Goertzel level stayed above
threshold permanently, preventing any tone OFF transitions and thus zero
character decodes.
Switch tone detection to use SNR (tone_mag / adjacent_band_noise_ref).
Both bands are equally amplified by AGC, so the ratio is gain-invariant.
Also replace the conditional noise_ref guard with unconditional blending
so the noise floor tracks actual ambient levels continuously.

The multimon-ng MORSE_CW decoder never reliably decoded characters.
Switch live decode to use the existing morse_decoder_thread() which
wraps MorseDecoder with Goertzel tone detection, adaptive thresholds,
and proper timing estimation — eliminating multimon-ng, PTY plumbing,
and the relay thread from the CW pipeline entirely.

Replace blocking rtl_stdout.read() with select()+os.read() so the
decoder thread emits diagnostic heartbeat scope events when rtl_fm
produces no PCM data (common in direct sampling mode). Add waiting-state
rendering in the scope canvas and hide the generic placeholder/status
bar for morse mode.

Add automatic gain control (AGC) before Goertzel processing to normalize
quiet audio from direct sampling mode where the -g gain flag has no effect.
Fix broken adaptive threshold bootstrap by adding a 50-block warm-up phase
that collects magnitude statistics before seeding noise floor and signal peak.
Lower threshold ratio from 50% to 30% for better weak-CW sensitivity.

Resolved conflict in static/js/modes/weather-satellite.js:
- Kept allPasses state variable and applyPassFilter() for satellite pass filtering
- Kept satellite select dropdown listener for filter feature
- Adopted upstream's optimistic stop() UI pattern for better responsiveness
- Kept optional chaining (pass?.trajectory) since drawPolarPlot can receive null

Correct modulation parameters (1200 bps, 2100/1300 Hz tones), replace
invented format codes with the six ITU-defined specifiers {102, 112,
114, 116, 120, 123}, accept all valid EOS symbols (117, 122, 127),
add parser validation (format, MMSI, raw field, telecommand range),
and fix truthiness bugs that dropped zero-valued fields.

Add synchronous startup verification after Popen() — sleep 0.5s and poll
the process before returning to the caller. If SatDump exits immediately
(missing device, bad args), raise RuntimeError with the actual error
message instead of returning status: 'started'. Keep a shorter (2s) async
backup check for slower failures.
Also fix --source_id handling: omit the flag entirely when no serial number
is found instead of passing "0" which SatDump may reject. Change start()
and start_from_file() to return (bool, str|None) tuples so error messages
propagate through to the HTTP response.
