feat: move user action buttons to detail page and fix full delete

- Add fullDeleteUser API method calling DELETE /admin/users/{id}/full
- Add Reset trial, Reset subscription, Disable, Delete buttons to AdminUserDetail info tab
- Implement inline confirm pattern (click → "Are you sure?" → execute, 3s timeout)
- Delete now calls /full endpoint removing user from bot DB and Remnawave panel
- Remove UserActionsMenu dropdown, ConfirmationModal and related code from AdminUsers list
- Update delete confirmation text in ru/en locales to reflect full deletion
