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.

- Fix globe destroyed on re-render by preserving canvas DOM node across
renderLocationCard() calls instead of recreating from scratch
- Reduce globe.gl camera minDistance (180->120) so globe is visible in
200px container
- Clear stale globeInstance ref when canvas is gone
- Enlarge CPU gauge (90->110px), percentage label (18->22px), core bars
(24->48px height), and detail text (11->12px)
- JS fetchLocation() now supplements server response with client-side
ObserverLocation.getShared() from localStorage when server returns
'default' or 'none', picking up manual coordinates from settings modal
- Location priority: GPS > config env vars > manual (localStorage) > default

- 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.
