AC: bind SmartCoolClean odor-controller option tokens; add Czech translation

- airconditioner.py: odor_controller_active binary_sensor + odor_controller_progress
  sensor, read from the /mode/vs/0 SmartCoolClean_/ProgressSmartClean_ option tokens
  (SmartThings cloud custom.airConditionerOdorController capability). Read-only --
  no confirmed write command.
- Reporter's TP1X_DA-AC-RAC-01001_0000 dump: fan speed and WindFree preset already
  bind via the existing composite climate entity, no code change needed there.
- en.json/nl.json: new entity names for the two additions.
- cs.json: new, full Czech translation catalog (mirrors en.json topology 1:1).
- New fixture + golden + tests locking in the odor-controller behavior.
