Add Home Assistant integration

Token-authenticated custom component exposing live per-club member counts
as sensors under a single "West Wood Club" device, fed by one coordinator
polling `/v1/Clubs/WhoIsInCount`.

Packaged via `buildHomeAssistantComponent` with a flake package + overlay so
it can be used in `services.home-assistant.customComponents`.
