* fix: add server-side sorting to user list, prevent client-side sort on paged data
The user management table applied client-side sorting to the current
page slice while pagination was handled server-side, causing ID-asc
views to show pages out of order (e.g. 23-42, 3-22, 1-2).
Backend: add sort_by/sort_order query params to GetAllUsers and
SearchUsers with a column whitelist for safe ORDER BY generation.
Frontend: pass sorting state to the API and reset to page 1 on sort
change. Generic useDataTable hook now disables client-side sorted row
model and sort UI for tables with manual pagination but no server-side
sort handler.
* fix: add id tie-breaker to non-unique sort columns, remove side effect from state updater
Append secondary ORDER BY id DESC when sorting by non-unique columns
(quota, created_at, etc.) to prevent row duplication/skipping across
OFFSET pages.
Move onPaginationChange out of setSorting updater to avoid side effects
inside a pure function (React Strict Mode double-invocation safety).
