- Fix SSE fanout thread AttributeError when source queue is None during
interpreter shutdown by snapshotting to local variable with null guard
- Fix branded "i" logo rendering oversized on first page load (FOUC) by
adding inline width/height to SVG elements across 10 templates
- Bump version to 2.26.0 in config.py, pyproject.toml, and CHANGELOG.md

ensureModeScript() used document.body.appendChild() to load lazy mode
scripts, but the preload for ?mode= query params runs in <head> before
<body> exists, causing all deep-linked modes to silently fail.
Also fix cross-mode handoffs (BT→BT Locate, WiFi→WiFi Locate,
Spy Stations→Waterfall) that assumed target module was already loaded.

Several modes didn't pass sdr_type to claim_sdr_device(), defaulting to
'rtlsdr' and triggering an rtl_test USB probe that fails for HackRF with
a confusing "check that the RTL-SDR is connected" message.
- Add sdr_type to frontend start requests for rtlamr, weather-sat, sstv-general
- Read sdr_type in backend routes and pass to claim/release_sdr_device()
- Add early guard returning clear "not yet supported" error for non-RTL-SDR
hardware in modes that are hardcoded to RTL-SDR tools
- Make probe_rtlsdr_device error message device-type-agnostic

The previous fix (f29ae3d) introduced a regression: when VIS parity
check failed or the VIS code was unrecognized, the detector entered
DETECTED state permanently and never resumed scanning. Now it resets
to IDLE on validation failure and only enters DETECTED on success.
Also resets partial image progress counter between consecutive decodes
and adds SDR device claiming to general SSTV route to prevent conflicts.

Adds a phosphor-persistence waveform scope showing audio RMS/peak
levels during ISS SSTV and General SSTV decoding, matching the
existing pager scope pattern with a purple color scheme.

Users can now manage decoded SSTV images with download and delete actions
accessible from hover overlays on gallery cards, the full-size image modal
toolbar, and a "Clear All" button in the gallery header. Both ISS and
General SSTV modes are supported.

slowrx is a GTK GUI app that doesn't support CLI usage, so the SSTV
decoder was silently failing. This replaces it with a pure Python
implementation using numpy and Pillow that supports Robot36/72,
Martin1/2, Scottie1/2, and PD120/180 modes via VIS header auto-detection.
Key implementation details:
- Generalized Goertzel (DTFT) for exact-frequency tone detection
- Vectorized batch Goertzel for real-time pixel decoding performance
- Overlapping analysis windows for short-window frequency estimation
- VIS header detection state machine with parity validation
- Per-line sync re-synchronization for drift tolerance

Adds a general-purpose SSTV decoder alongside the existing ISS SSTV mode,
supporting USB/LSB/FM modulation on common amateur radio HF/VHF/UHF
frequencies (14.230 MHz USB, 3.845 MHz LSB, etc.) with auto-detection
of modulation from preset frequency table.
