Code Review

This pull request introduces bookmarking and reporting features, including database schema updates, new API endpoints for admin and user actions, and corresponding frontend components. It also improves the authentication flow by redirecting unauthorized domains and adds automated tooltips for accessibility. Feedback was provided regarding the inconsistent use of server-side versus client-side timestamps for database updates and a suggestion to refactor string trimming logic for better readability.

Using sqlnow()for thenowvariable inside a transaction is fine, but it is inconsistent with the use ofnew Date().toISOString()` elsewhere in the same file (e.g., in the draft publish route). It is better to use a consistent approach for timestamps to avoid potential timezone or format discrepancies.

The content field is being trimmed before being sent to the API. While this is good, the validation logic on line 59 already checks content.trim().length < 1. It would be cleaner to perform the trim once and store it in a variable before validation and API call.
