(ddp-removal): swap /api/v1/method.call/addUsersToRoom for the per-type

[github-actions]

REST endpoints (/v1/channels.invite or /v1/groups.invite). The federation
suite still asserts the legacy DDP error shape (message field with a
stringified { error: { error } }); migrating requires updating those
expectations to the REST envelope ({ success: false, error }).

I am working on the issue

[yummyPancake2607]

This PR #40740 migrates federation add-user tests from legacy DDP response assertions to REST response envelopes as part of the DDP removal cleanup.

I’ve verified:

• ESLint passes
• federation tests pass locally
• slash command DDP behavior remains unchanged intentionally

Could someone please review and approve the workflows when available? Thanks!
