Fix typing of ConfigEntry in WLED

[mik-laj]

Breaking change

Proposed change

This PR updates the WLED integration to use a custom typed ConfigEntry (WLEDConfigEntry) in the async_get_options_flow method signature instead of the generic ConfigEntry type. This aligns with a pattern used in other integrations to provide better type safety when accessing config entry runtime data and it is required by strict-typing rule. No behaviour change, but it is needed to make linter happy.
