…e API resources (#4237)

* feat: Add API token generation and authentication

This commit introduces API token generation and authentication for write operations.

- Adds a section to the user's profile edit page to generate and display an API token.
- Reuses the `authentications` table to store the API token, avoiding the need for a database migration.
- Implements token-based authentication for the API using the `Authorization: Token token=...` header.
- Enables write operations for all API resources and ensures they are protected by the new authentication mechanism.
- Adds feature and request specs to test the new functionality.
