Add configured room creation to administration

Create an explicitly owned new host seat with supported rules/modules and ordered AI seats through one live-authorized transaction. Save exact account-bound retries across refresh, record durable audit metadata, and never restore a revoked or transferred host credential. Connect invitation joining and ordinary voluntary host handover. Preserve normal readiness and Advanced preview gates.

Verified types, lint, 5240 offline tests, 52 HTTP tests and build. Eight authenticated HTTP groups and independent privacy/persistence review passed. Browser QA confirmed one room after a lost response and refresh/retry, working host controls and saved continuation. Mobile layout passed; requested desktop viewport override did not take effect. Existing games preserved. Authenticated deployed administrator acceptance remains pending explicit QA access.
