feat(system-control): Tier 0/1 controls with no device-owner dependency (#160) (#169)
* feat(system-control): Tier 0/1 controls with no device-owner dependency [#160]

Track A of the system-control split (Track B = device owner, shipped in #168). Ships the
capabilities that need NO device owner, with graceful per-tier degradation.

Capability reporting (keystone):
- DeviceInfo now reports can_write_settings / accessibility_enabled / overlay_granted
  alongside the existing tier/device_owner flags; server persists them (3 additive device
  columns, older APKs default to 0); dashboard gates controls + shows what's grantable.

Android SystemControl (new, all best-effort / no-op when unsupported):
- Tier 0 (no permission): media volume (AudioManager STREAM_MUSIC), per-window brightness
  (WindowManager.LayoutParams.screenBrightness — dims our window only).
- Tier 1 (WRITE_SETTINGS): system-wide brightness + screen-off timeout (Settings.System).
- Commands set_volume / set_brightness / set_system_brightness / set_screen_timeout wired
  in MainActivity.onCommand; ALLOWED_COMMANDS extended for the group path.
- SetupActivity gains a one-time WRITE_SETTINGS grant row (mirrors the overlay/accessibility
  grants); manifest declares WRITE_SETTINGS.

Dashboard:
- device-detail "System control" section (any Android panel): volume + this-app brightness
  sliders always; system brightness + sleep-timeout only when the panel reports
  can_write_settings, else a "grant on the panel" hint. Sends on release (not drag).

Validated live on a non-owner tier-0 panel: dashboard → set_volume 0.75/0.15 → the panel's
STREAM_MUSIC volume moved to 11/2 (of 15). 423 server tests green.

Closes #160.

* fix(system-control): volume slider reflects real volume + device-owner brightness/timeout [#160]

Two fixes from live testing:

1. Volume "doesn't remember" — the slider hardcoded 50 because the panel never reported its
   current volume. Now DeviceInfo reports media_volume (0..1); a new lightweight device:info
   socket event lets the panel re-report right after a set_volume (no full re-register / playlist
   re-push); server stores devices.media_volume; the dashboard inits the slider from it.
   Validated: dashboard set_volume 0.60 -> panel STREAM_MUSIC 2->9 (of 15) -> stored 0.60.

2. System brightness/timeout on a DEVICE OWNER — was gated only on WRITE_SETTINGS, which an
   owner doesn't have. A device owner can set those via DevicePolicyManager.setSystemSetting
   with no grant, so SystemControl now takes that path when isDeviceOwner(), and the dashboard
   enables the Tier-1 controls when can_write_settings OR tier===2. STPolicy.setSystemSetting added.

deviceSocket device_info UPDATE extracted into applyDeviceInfo(), shared by device:register and
device:info. Migration: devices.media_volume REAL (additive). 423 server tests green.

* feat(system-control): brightness/timeout remember + move controls into a tab [#160]

Same "remember what it's set to" treatment as volume, now for brightness + sleep timeout, and
the System control section moves off the top into its own "Controls" tab.

Reporting (DeviceInfo -> device:info re-report -> devices columns -> dashboard slider init):
- system_brightness (read from Settings.System, no permission) + screen_off_timeout_ms.
- window_brightness: persisted in ServerConfig (survives relaunch, re-applied on MainActivity
  launch) so the per-window slider reflects it too.
- reportInfoNow() now also fires after set_brightness / set_screen_timeout.

Dashboard: new "Controls" tab (any Android panel) holding the volume/brightness/timeout controls;
every control inits from the reported value; sleep dropdown preselects the current timeout.

Server: +3 additive columns (system_brightness, window_brightness, screen_off_timeout_ms); the
device_info UPDATE stores them. Migrations all additive/re-runnable. 423 server tests green.

Validated live: set_brightness 0.40 -> stored window_brightness 0.40; volume 0.30 -> 0.33.
