feat: Improve room naming and data integration

[allenporter]

Simplify how we track unset names by adding a raw_name field on NamedRoomMapping.

This also adds other helper methods to the containers to simplify the code in the traits. The traits are changed to have fewer functions with side effects that mutate data on the trait, and removing duplicate checks for empty lists or value types.

Pull request overview

This PR simplifies room naming tracking in the Roborock integration by introducing a raw_name field on NamedRoomMapping and converting the existing name field to a computed property that provides a fallback default. It also adds helper methods (rooms_map, rooms_name_map, named_room_mapping, iot_id) to container dataclasses to centralize common lookups, and simplifies trait logic to reduce side effects and duplicate checks.

Changes:

• Replaced the name field on NamedRoomMapping with an optional raw_name field and a name property that falls back to "Room {segment_id}" when raw_name is unset.
• Added helper properties (rooms_map, rooms_name_map, named_room_mapping, iot_id) to HomeData, MultiMapsListMapInfo, MultiMapsListRoom, CombinedMapInfo, and HomeDataRoom containers.
• Simplified RoomsTrait.refresh() and HomeTrait._refresh_map_info() to use the new helpers and reduce mutation and duplication.

Could it be worthwhile to set .rooms to a property? I'm figuring we do this other places as well, may be easier to just know we can always assume it is a list. Not needed for this PR though, just a thought

[allenporter]

Would it be current_rooms?

[Lash-L]

I think that makes sense!

[allenporter]

This depends on one of the map infos returned from an RPC before it is saved so I don't think this works. I still added the attribute, but it won't make this code simpler.

Up to you if you want to do the property - looks good otherwise
