Enhance redirect URL handling and MentionParser functionality

- Updated the `redirect_url` validation in `UserFormRequest` to accept strings instead of just max length.
- Modified `MentionParser` to include a `urlFriendlyOutput` method, allowing for URL encoding of special characters in parsed values.
- Adjusted the `PublicFormController` to utilize the new `urlFriendlyOutput` method for redirect URLs.
- Created a migration to change the `redirect_url` field type in the database from string to text, accommodating longer URLs.
- Added tests to ensure proper handling of long redirect URLs and the functionality of the new URL-friendly output feature in `MentionParser`.

This update improves the flexibility and robustness of form handling and URL processing.
