Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* Revert "fix: allow workspace owner to edit datatable config for fork setup"

This reverts commit ab683e637b.

* refactor: move datatable fork setup into create_workspace_fork backend

Instead of updating datatable settings from the frontend after fork
creation (which required admin/owner access), pass forked_datatables
info to create_workspace_fork and handle it atomically in the same
transaction. Removes applyPostForkDatatableUpdates from frontend.

Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>

* fix: snapshot schema in backend during fork instead of frontend

The schema snapshot is now taken by the backend in apply_forked_datatable
via snapshot_datatable_schema, which connects to the parent workspace's
datatable and runs pg_get_full_schema. This removes the need for the
frontend to call getDatatableFullSchema and pass the schema through.

  (fork owner or super admin)
- validate_dbname on target_dbname_override and ForkedDatatableInfo.new_dbname
- Enforce wm_fork_ prefix on forked datatable new_dbname
- DumpFile: set /tmp/windmill/ to 0700 and create files with 0600
