feat(workspaces): add statistics and metrics

Expose aggregate translation health and historical trends at workspace scope. Keep metric lookups integer-indexed and batch the management listing to avoid per-workspace queries.

 .. rubric:: New features
 
+* Workspaces now provide aggregate translation statistics and historical metrics.
 * Added API endpoints for listing, adding, accepting, rejecting, and voting on translation suggestions.
 * :doc:`Translation reports </devel/reporting>` are now generated in the background, stored for later download, available at workspace scope, and include translator work analysis.
 * Added :guilabel:`Use keywords exclusively` option to :ref:`addon-weblate.gettext.xgettext`, allowing projects to disable xgettext default keywords and rely only on a custom keyword.
