* chore: improved pat permissions

* fix: err message

* [WEB-4330] refactor: update API token endpoints to use user context instead of workspace slug

- Changed URL patterns for API token endpoints to use "users/api-tokens/" instead of "workspaces/<str:slug>/api-tokens/".
- Refactored ApiTokenEndpoint methods to remove workspace slug parameter and adjust database queries accordingly.
- Added new test cases for API token creation, retrieval, deletion, and updates, including support for bot users and minimal data submissions.
