Hisense VIDAA projector control

The VCP view now exposes a Hisense VIDAA card for displays whose EDID vendor is HEC (including the C1). Enter the projector IP; LittleBigMouse derives the controller MAC from the network route, including across routed subnets. The projector MAC is optional and is only used for Wake-on-LAN. Navigation keys are sent over the local VIDAA MQTT endpoint (TLS, port 36669); Wake uses a standard broadcast magic packet.

Before pairing, LittleBigMouse reads the projector's UPnP descriptor directly by IP and selects the protocol from transport_protocol. Older RemoteNOW devices such as the C1 (2160) use the static MQTT service credentials and a <CONTROLLER MAC>$normal topic. Newer VIDAA devices use time-based credentials and access tokens. If the descriptor is unavailable, the newer credential algorithms are tried in order.

The C1 requires the private client certificate shipped in the official Android VIDAA application. It cannot be redistributed with LittleBigMouse. Extract the PKCS#12 file (client_mobile_android.p12, or res/3R.p12 in obfuscated APKs) and copy it to ~/.config/LittleBigMouse/vidaa-client.p12. The password is detected internally. The connection uses mutual TLS 1.2, then displays the projector PIN and stores the issued VIDAA access tokens.
