feat(devices): BLE LED controller support (SP110E/Triones/Zengge/Govee)

End-to-end BLE streaming: provider + client + per-protocol wire encoders
with whole-strip averaging, desktop (bleak) and Android (Kotlin BleBridge
via Chaquopy) transports, discovery with protocol-family detection that
auto-fills the UI, throttled not-connected warning + 10 s reconnect
cooldown so a dropped link no longer stalls the pipeline at ~30 s/frame,
and an explicit asyncio.wait_for wrapper around bleak connect() since
the WinRT backend doesn't always honor the timeout kwarg.

Also rewrites server/restart.ps1 to be parameterized (-Port / -Module /
-PythonVersion / timeouts / -Quiet), pick the right interpreter via the
py launcher, pre-flight the target module, poll port readiness on both
shutdown and startup, redirect child stdout/stderr so Start-Process
doesn't hang on inherited Git-Bash handles, and return proper exit codes.

Rolls in concurrent work: Android BLE permissions + launcher icons + ru/zh
resources, Chaquopy-safe value_stream psutil fallback, setup-required
modal, asset-store test coverage, and misc system/config touch-ups.
