Allow administrators to centrally set/force the Database Language for all users

Currently, each user's "Database Language" setting (Administration → Users) defaults to the language RDM detects from that user's Windows Regional Settings. There is no way for an administrator to centrally force this setting to a specific language (e.g., English) across all users in the data source.
Use case: Organizations with users across multiple locales want a consistent language (typically English) for shared/administrative purposes, regardless of each user's individual OS regional settings. Today this requires manually changing the Database Language setting per user, which doesn't scale and gets reset per-user based on OS locale.
Requested behavior: Add an admin-level control (e.g., in Data Source / Administration settings) to set a default or enforced Database Language value that applies to all users, overriding the per-user Windows Regional Settings detection.
