Removed default value for blogname in profiles table

I recently removed the default value for the blog name in the profiles table. This change helps ensure that each blog entry is unique and intentionally set by the user. It's a small tweak, but it promotes better data integrity and user input.

Updated middleware to improve webhook handling and logging

I've refined the middleware for Clerk, focusing on webhooks. Originally, the middleware was processing too much. After tweaking, it now ignores unnecessary webhooks, streamlining the process. I also improved logging for the Clerk auth webhook. Clearer logs make debugging easier and help maintain a smooth operation.

Added informative popovers to the dashboard

To enhance user experience, I've added popover info-boxes across all dashboard tabs. These informative guides help users understand what each control does, reducing confusion and improving usability. It's a step toward making JustVibeCoding more user-friendly without overwhelming them with documentation.
