Fix deprecated config_entry assignment in options flow

Remove explicit self.config_entry assignment in OptionsFlow __init__
method, which is deprecated and will break in Home Assistant 2025.12.

**Issue:**
The integration explicitly assigns self.config_entry in the options flow
constructor, which is deprecated. Modern Home Assistant automatically
makes config_entry available to options flows without manual assignment.

**Fix:**
- Removed __init__ method from LockCodeManagerOptionsFlow
- Updated async_get_options_flow to return flow without passing config_entry
- Home Assistant now automatically injects config_entry into the flow

**Location:**
- custom_components/lock_code_manager/config_flow.py:315

**Benefits:**
- Eliminates deprecation warning
- Uses modern Home Assistant API
- Cleaner code with less boilerplate

Fixes TODO #3 - Breaking change deadline: HA 2025.12
