chore: deprecate checkFederationConfiguration meteor method

[KevLehman]

Proposed changes (including videos or screenshots)

Adds a deprecation warning to the checkFederationConfiguration meteor method, following the standard methodDeprecationLogger.method pattern.

The method belongs to the old Matrix bridge federation stack and was only reachable through the hidden Federation_Matrix_check_configuration_button action setting, which is being removed in 9.0.0 (#41908). It has no other callers in the codebase and no replacement endpoint.

Issue(s)

Steps to test or reproduce

Call the checkFederationConfiguration meteor method — the server logs the deprecation warning and increments the deprecation metrics.

Further comments

Removal targeted at 9.0.0 alongside the Matrix bridge settings removal (#41908).

Task: CORE-2623

Summary by CodeRabbit

• Chores
  • Marked federation configuration checking as deprecated.
  • Existing validation and configuration checks remain unchanged.
