Fix influx-v2 missing dep, boolean conversion, and connectivity persistence

1. Add missing @influxdata/influxdb-client dependency: the influx-v2
   plugin imports it but it wasn't in package.json, blocking
   generate:openapi on CI. Pre-existing issue on main.

2. Fix boolean conversion for all device types: convertValueForZigbee
   only converted booleans for the 'state' key. Other boolean-typed
   properties (lock_state, fan_state, etc.) also need conversion since
   toZigbee converters expect strings ("ON"/"OFF", "LOCK"/"UNLOCK").
   Now converts all boolean values regardless of key name.

3. Fix optimistic lastDbState update: was set before the DB write,
   so if setConnectionState threw or the device wasn't adopted yet,
   the state was marked as persisted and never retried. Now only
   updates lastDbState after successful setConnectionState call.
   Failed writes and unadopted devices will retry on the next cycle.
