fix: restore build and stabilize E2E cross-signal behavior

Revert the automated member-ordering pass that broke Angular field init
(TS2729) and disable that rule until a safe reorder strategy exists.
Fix modal/confirm dialog i18n defaults via template fallbacks, search all
active endpoints (including offline), register foreign rooms with actor
owner IDs, sync profile display names from avatar summaries, and guard
dm-chat when a private call converts to a group conversation.
