Subject: [PATCH] feat(home-assistant): enable OTBR for ZBT-2 + add HA
 otbr/thread components

Brings up otbr-agent against the ZBT-2 over Spinel/UART, opens the
REST API on :8081, and wires HA's otbr + thread integrations so
Matter-over-Thread devices can commission through the existing
matter-server.
