jpmschweitzerandClaude Opus 4.8 cdb23bda05 feat(firmware): volume control goes to eleven

Rework the speaker volume from a 0-100 percentage to an 11-step level
(0..11, mapped to the codec's percent), with mute that remembers the
prior level so unmute restores it. Any non-silent change plays the gong
as feedback; a new change cuts the in-flight gong off and restarts it
rather than queueing another. The tap overlay shows the level number and
0..11 bar, and a "11" drifts up off the bar when you hit maximum.

Also lands the device side of gateway volume commands: gw_client routes a
"command" message to face_volume_command, which applies the change and
shows a compact auto-hiding volume HUD (a centered bar) — the gateway
half that sends these lives in a following commit.

The format is based on Keep a Changelog. DeskLock is pre-release and unversioned; entries accumulate under Unreleased until the first tagged release.

[Unreleased]

Added

Tap the screen to reveal on-screen controls — a microphone button plus volume down/up and a live level bar, using Phosphor icon glyphs. Tapping the dimmed backdrop dismisses them.

Fixed

Fixed the blue-screen flicker during voice activity — the matrix rain now renders as cheap pre-rendered sprites, and the DSI clocks/FIFO are tuned, so the display's memory reads are no longer starved by Wi-Fi and audio DMA.

Changed

Volume is now an 0–11 scale (it goes to eleven) with a gong cue on each change and a little "11" that floats off the bar at maximum.
Matrix rain is drawn from a reused pool of pre-rendered streak sprites instead of live text labels, and eases off while the device is listening or speaking.
