v0.6.4 — Fix 500 in options flow on modern HA

Fixed

• Removing __init__ from the options flow handler. Modern Home
  Assistant (2024.11+) injects self.config_entry itself and writing
  to that attribute from our own constructor produced a 500 error
  when the user clicked the Configure cog. With the constructor gone
  the framework wires everything up correctly and the options dialog
  loads as expected.
