v0.3.8-rc2

Builds on the React SPA web console and closes most of the gap with the desktop head. Everything here is server-side + SPA only — no change to the video pipeline, the desktop UI, or the mobile heads.

Live grid

• Stills mode — periodic snapshots instead of live streams, refresh interval
  2–60 s. A 25-cell wall costs one HTTP GET per camera per interval instead of an
  ffmpeg session each; the camera encodes the JPEG itself when it runs Majestic.
• Digital zoom in a tile: mouse wheel, drag to pan, buttons for touch. The
  transform lives on the tile's slot, never on the pooled <video>, so zoom
  can't follow a camera into another cell.
• Kiosk mode — chrome-free full-viewport wall with optional page cycling.
  Uses the Fullscreen API when granted and falls back to a fixed overlay when it
  isn't (embedded/iframed pages refuse it outright).
• Wall preferences live in the browser, not the install: the same layout is
  watched from a control-room screen and from someone's laptop.

Archive

• Recording start/stop from the browser, written into the same folder and table
  the desktop head uses (-c copy, segmented, q on stdin so the MP4 trailer is
  written).
• Calendar + date filtering, paging, and clip export (fast -c copy or precise
  re-encode), streamed as a download without leaving a copy on the server.
• Playback is a ranged file response, so seeking is the browser's own.

Snapshot library

• Stills taken from the browser can be kept: same folder layout, same
  .thumbs/<id>.jpg naming and the same table as the desktop's
  SnapshotService, so a still taken from a phone shows up in the desktop
  gallery and vice versa.
• Thumbnails are produced with ffmpeg — already a dependency of this head —
  rather than pulling the Video layer's Skia thumbnailer into the server.
• Pixel dimensions are read from the JPEG frame header; no imaging library
  needed to record what the desktop records.
• Gallery page with lightbox, download and delete, under the Archive tab.

Camera settings (Majestic)

• Read the live config.json, edit fields, post raw JSON, set day/night, read
  /metrics. Schema-driven like the desktop editor (IMajesticConfigSchema), so
  it renders whatever knobs the firmware actually exposes instead of a fixed form
  that drifts between builds.
• ISP fields get their own panel: Majestic re-reads those live, so tuning the
  picture does not restart the encoder. Fields that do restart it are flagged.
• Edits travel as (path, value) and are applied against a freshly read copy of
  the camera's config, so a stale tab can't revert someone else's change.

Two-way audio

• Listen: audio rides in the existing live stream (transcoded to AAC, ~1% of
  the video bitrate) rather than a second session, so nobody's picture restarts
  when they unmute.
• Push-to-talk: the browser sends 16-bit PCM over a WebSocket; G.711
  encoding and RTP packetizing happen server-side in the same Core code the
  desktop talks with. One talker per camera — a speaker is exclusive.
• Held, not toggled, and the camera is released when the route changes.

Permissions

• New Talk flag, separate from Ptz/Manage: it is the one action that
  reaches people standing in front of the camera.
• ViewArchive now gates the archive and the snapshot library; Export gates
  clip export. Both flags previously existed without gating anything.
• Camera settings are Manage-only including reads — config.json carries
  the camera's own logins and, on many builds, the Wi-Fi PSK.

Fixes

• The live WebSocket was write-only, so a viewer's close frame went unnoticed and
  the shared ffmpeg process outlived its last viewer. Verified: 8 streams → 0
  after the last tile releases.
• A camera that never answered a Majestic call was reported as success (204): our
  own call deadline surfaced as the same cancellation as an abandoned request.
  Now 504.
• Player: a viewer joining an already-running stream got a buffer starting at
  t=90s with currentTime=0 and sat paused forever. A watchdog now jumps to the
  live edge.
• ViewArchive was missing from the users page, which quietly made the archive
  ungrantable to anyone created from the web console.
• Recording a camera that delivered nothing left a 0-byte file and an archive row.

What's Changed
