feat: Home Assistant API tools (ha_get_state, ha_get_states, ha_call_service)

Register three HA orchestrator tools so Inara can read device states and
control devices via the HA REST API. ha_call_service requires admin role
and user confirmation. Also includes accumulated UI fixes (setProcessing
helper, wasNewSession flag cleanup).
