Merge origin/main into main

Integrate upstream updates while preserving the local analytics dashboards and schema-only migration changes.

Combine user account analysis with upstream user/group usage statistics in separate tabs, retain all migration versions, and keep the deleted audit document removed.

Validation: gateway all-target cargo check, frontend type check and 57 focused tests, 48 migration tests, schema composition checks, and diff whitespace checks.
