fix: update function parameters and exception handling

See merge request !8

- Removed redundant entries from phpstan-baseline.neon where exceptions were indicated as not being
thrown
- Corrected the function parameters in `src/QUI/Auth/Facebook/Auth.php` to handle `null` inputs for
`getTitle` and `getDescription` methods
- Adjusted the `activate` method call in `src/QUI/Auth/Facebook/Facebook.php` to pass an empty
string where false was previously given due to function signature mismatch
- Updated exception handling across multiple files by specifying the fully qualified namespace of
`QUI\\Exception`
- Modified function parameters in `src/QUI/Registration/Facebook/Registrar.php` for `getTitle` and
`getDescription` to handle `null` inputs
