New `camera` module in modules.example.yaml (and the embedded copy) with
four functions: `set` (any control=value list, incl. preset/colour buttons),
`toggle` (flip between two values), `adjust` (step a numeric control by a
delta, clamped to the min/max parsed from `cameractrls -l`, with optional
`extra` controls applied first), and `is` (poll helper, exit 0 on match).
Device comes from CAMERA_DEVICE in .env (default /dev/video0) or a per-key
`device` param. cameractrls exits 0 for unknown controls, so polls must
use `is`; stderr is discarded to drop Python deprecation warnings.
README: Camera module section with setup, function table, a folder
example, and the oksvg viewBox-offset centring gotcha for SVG icons.

Add "; charset=utf-8" to the JSON Content-Type header so Slack's
users.profile.set no longer returns the missing_charset warning.

Introduce a per-key `text_command` + `refresh` feature: the service
periodically runs a shell command and renders its stdout as the key's
text overlay, compositing over the base icon (or a black background for
text-only keys) each tick. `text` acts as the static fallback shown
before the first run or when the command errors/outputs nothing. A
refresh goroutine owns the key's image and also handles an optional poll
block (choosing icon_true/icon_false per tick). Adds `$(...)` sugar in
`text` as shorthand for `text_command`.
- internal/config: add TextCommand/Refresh fields to KeyConfig
- cmd/streamdeck: refreshTextKey goroutine, runTextCommand, unwrapCmdSubst
- config.example.yaml: document the feature with a `flow` pomodoro
live-countdown example (status --short, toggle/skip/stop/gui)
- modules.example.yaml: example config updates
