gsxdsm 716f3964c5 FN-5790: harden room chat send handling and optimistic reconciliation ...

Prevent duplicate room sends and avoid restoring composer text when ambiguous failures still delivered the message.

- guard room composer sends with an in-flight ref to prevent double-dispatch
- treat ambiguous post-send refresh failures as delivered when recovery confirms the user message
- centralize optimistic/SSE user-message reconciliation to replace temp messages instead of duplicating them
- add and update chat room hook/component tests that cover double-send prevention and delivered-on-ambiguous-failure behavior
- add a patch changeset for @runfusion/fusion documenting the room chat reliability fix
