Fix OptionsFlowHandler initialization - config_entry is read-only property

[Copilot]

OptionsFlowHandler.__init__() attempted to assign self.config_entry = config_entry, but the base class OptionsFlow provides config_entry as a read-only property, causing AttributeError: property 'config_entry' of 'OptionsFlowHandler' object has no setter.

Changes

config_flow.py:

• Removed config_entry parameter from OptionsFlowHandler.__init__()
• Removed manual assignment to self.config_entry
• Added lazy initialization in async_step_init() to load counters from self.config_entry.options on first access
• Updated async_get_options_flow() to instantiate handler without arguments

Before:

def __init__(self, config_entry: ConfigEntry) -> None:
    self.config_entry = config_entry  # AttributeError here
    self._counters = list(config_entry.options.get("counters", []))

After:

def __init__(self) -> None:
    self._counters: list[dict[str, Any]] = []
    # config_entry is automatically available via base class property

async def async_step_init(self, user_input: dict[str, Any] | None = None) -> FlowResult:
    if not self._counters:
        self._counters = list(self.config_entry.options.get("counters", []))

Version bumped to 1.4.1 with corresponding changelog entry.
