hotfix: improve mimetype creation and dashboard data loading

- Updated the file download route in `start/routes/api.ts` to include "file" in the path.
- Corrected the validation message key for file extension minLength in MimetypeController.ts.
- Updated favicon path in `resources/views/app.edge`.
- Added argon2 dependency in `package.json`.
