Fix app becoming unresponsive when two browser windows are open: the
root cause was HTTP/1.1 connection pool exhaustion (6-connection limit
per origin). VoiceAlerts was opening 3 SSE streams per window by
default, so two windows produced 8 connections and permanently starved
all regular HTTP requests.
- voice-alerts.js: default all streams to false (opt-in) to stay within
the browser connection limit; existing user preferences in localStorage
are preserved
- routes/alerts.py: replace direct AlertManager.stream_events() with
sse_stream_fanout so both windows receive every alert instead of
competing for the same queue
- routes/bluetooth_v2.py: same fanout fix via subscribe_fanout_queue,
preserving named SSE events (device_update, scan_started, etc.)
Also includes accumulated UI/theming changes: accent-cyan CSS variable
sweep across mode CSS/JS files, standalone dashboard pages, template
updates, satellite TLE data refresh, and tile provider default rename.

Add theme-aware severity/neon CSS variables and replace hardcoded hex
colors (#fff, #000, #00ff88, #ffcc00, etc.) with var() references
across 26 files so text remains readable in both dark and light themes.

Add .gitignore entry for data/subghz/captures/ to prevent large
IQ recording files from being committed.

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.

Shows the current VIS detection state machine position (Idle, Leader,
Break, Start bit, Data bits, etc.) in the signal monitor. This helps
diagnose why decoding may not be starting - e.g. if the VIS detector
is stuck in Idle despite a leader tone being present, the signal may
not contain a valid VIS header.

Shows RMS audio level bar and SSTV tone classification (leader/sync/noise)
via SSE during detecting mode, replacing the static "Listening..." state
with actionable signal feedback.

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.
