fix: Revert room-details DTO extras that broke room parsing

af0d7b6 added RankingContext/DataBlob/MaxPlayers/ToxmodEnabled to the
shared BuildRoomServerDetails (and DataBlobHash/Description to
BuildStudioSaveWire) to try to satisfy the 2023 SaveRoom commit-response
Dispose walk. The invented RankingContext object shape is rejected by
the strict room-details mapper, so GET rooms/{id} (and every room list
that shares the builder) failed with "Malformed Response" -> rooms
broke. The 2023 mappers validate value SHAPES, not just key presence, so
bolting unverified keys onto the shared room DTO is unsafe.

Reverts af0d7b6 code changes. Room saving remains functionally correct
(blob persists, fanout delivers); the SaveRoom success toast is left for
a separately-verified fix.
