Debug post deletion redirect error

when i deleted a post, i saw an application error instead of being redirected to the repo index. next.js bug? or our bug?

Our bug, not Next.js! 🐛

I found and fixed the issue. Here's what was happening:

##The Problem

When you delete a post, both delete dialogs were calling:

router.push(`/${owner}/${repo}`)  // Navigate to repo index
router.refresh()  // Refresh the page

The router.refresh() after router.push() creates a race condition. The server action deletePost also calls updateTag(post:${postId}) which tells Next.js to revalidate the post page cache. When refresh() runs, Next.js tries to re-render the current page (the now-deleted post), which fails because the post no longer exists.

##The Fix

1. delete-comment-dialog.tsx: Only call router.refresh() when staying on the same page (i.e., when deleting a comment, not the whole post)
2. moderator-delete-post-dialog.tsx: Remove router.refresh() entirely since we're always navigating away
