Add 'wasm-unsafe-eval' to script-src and blob: to worker-src in
Content-Security-Policy header. Required by onnxruntime-web to compile
the Silero VAD ONNX model. Also surface VAD init errors as a toast
instead of silent console log.

Swaps useSilenceDetector for useVad. Adds no-speech guard: when the
user manually stops recording without VAD ever detecting speech, show
a toast and skip the Whisper round-trip instead of sending pure noise.

Phase B of chat view refinement. Bumps chat reading column to 1200px,
lifts the RAG scope chip out of the footer and into the ChatView header
(next to the title), and collapses the listen toggle / volume slider /
stop-playback buttons into a single speaker popover on the input bar.
Listen mode + TTS are now available in briefing and workspace chats too,
since the controls live on the shared ChatInputBar.

The web silence detector previously ran RMS over getByteFrequencyData
bytes (which are already dB-scaled) and re-log'd the result, producing
numbers that didn't line up with real dBFS. Combined with a static
-40 dB threshold that sat right on top of room ambient, silence
detection rarely fired and the user had to click stop manually.
- Rewrite useSilenceDetector to use getFloatTimeDomainData for honest
linear RMS → dBFS.
- Silence threshold is now dynamic: track session peak dBFS and treat
"silent" as 15 dB below peak. Auto-calibrates per mic/room.
- Grace period (1500 ms) at start so the user can begin speaking
before checks arm; static -45 dB fallback until peak clears -25 dB
so dead-silent sessions don't spin forever.
- Silence duration bumped 1500 → 2000 ms for breathing room.
Visual: detached red radial-gradient disc sits behind the mic in a
wrapper; the button no longer scales, so the white mic icon stays
legible on top while the halo grows from 1x to ~2.6x with live
amplitude. Much more obvious "you are live" signal than the prior
subtle box-shadow pulse.

The mic button now scales and glows proportional to the silence
detector's RMS amplitude instead of sitting static. Gives obvious
feedback that audio is actually being picked up — silence still
breathes via a 0.1 floor, loud input caps at ~1.18x scale so it
doesn't punch through the input bar.
