Fix quill and mentions (#758)

* Enhance MentionParser and Related Components for Improved Mention Handling

- Updated `MentionParser.php` to support the `mention="true"` syntax, allowing for more flexible mention parsing.
- Added tests in `MentionParserTest.php` to verify the handling of mentions with the `mention="true"` attribute, including support for URL-encoded field IDs.
- Refactored `MentionInput.vue`, `MentionDropdown.vue`, and `RichTextAreaInput.client.vue` to ensure consistent use of `mention-state` and improve mention dropdown functionality.
- Enhanced `quillMentionExtension.js` to better manage mention data and improve integration with Quill editor.

These changes aim to improve the functionality and reliability of the mention feature across the application, ensuring a better user experience.

* Refactor FormInformation Component for Improved Logic and Structure

- Updated `FormInformation.vue` to utilize the composition API with script setup syntax, enhancing readability and maintainability.
- Replaced `v-if` condition for form visibility with a computed property `isFormClosingOrClosed` for better clarity.
- Streamlined data handling by converting data and computed properties to reactive state and computed properties, respectively.
- Improved the copy settings logic to utilize refs, ensuring proper state management.

These changes aim to enhance the overall structure and functionality of the `FormInformation` component, providing a better user experience and code clarity.
