🔧 fix(Shared Links): Handling Shared Link Errors

[ohneda]

Summary

Resolved an issue where the client would not display an error message when the API encountered an error while creating or updating a shared link.

ref: #2772 (comment)

Details

Added the error handling for shared link operations:

• Implemented error message display on the client side when the API returns an error.
• Modified the backend to return HTTP status code 500 when an error occurs during processing.

This PR includes exception handling in both the model and the router. However, it might be more appropriate to handle exceptions only in the router and not in the model. Please let me know if any adjustments are needed to maintain consistency with other parts of the codebase.

Change Type

• Bug fix
• Translation update

Testing

Manually verified the following scenarios:

• When creating a shared link, an error message is displayed if the API returns a 4xx or 5xx error.
• When updating a shared link, an error message is displayed if the API returns a 4xx or 5xx error.
• When deleting a shared link, an error message is displayed if the API returns a 4xx or 5xx error.
• When displaying the list of shared links, an error message is displayed if the API returns a 4xx or 5xx error.
