ESC-539 - Refactor SignatureInput Component for Consistency and Enhanced Logic (#749)

* Refactor SignatureInput Component for Consistency and Enhanced Logic

- Updated the `SignatureInput.vue` component to use `InputWrapper` instead of `input-wrapper` for consistency with naming conventions.
- Added logic to reset the signature field value when the model value is an array, improving handling of Notion database data.
- Enhanced the `mounted` lifecycle hook to ensure the signature pad canvas is resized correctly after rendering.
- Improved error handling in the file upload process by capturing the error in the catch block.

These changes aim to enhance the maintainability and functionality of the `SignatureInput` component, ensuring better user experience and consistency across the codebase.

* Refactor SignatureInput Component to Remove Unused ModelValue Logic

- Removed the modelValue handler logic from the `SignatureInput.vue` component, simplifying the component's state management.
- Cleaned up the created lifecycle hook by eliminating unnecessary checks related to Notion array data handling.

These changes aim to enhance the maintainability of the `SignatureInput` component by streamlining its logic and improving overall code clarity.

* fix lint
