Move aggregate triggers from write to relay confirmation

[Copilot]

Aggregate counts (comment/vote counts) were being incremented when records were written with status: "pending", but the UI filters out pending records. This caused mismatches where "1 comment" displayed but no comment appeared.

Changes

Modified createComment, createPostVote, createCommentVote:

• Aggregate triggers now only fire when status === "live"
• Pending records no longer affect counts until confirmed by relay

Modified updateComment, updatePostVote, updateCommentVote:

• Added detection of pending → live status transitions
• Triggers fire when relay confirms the record

Flow

// API layer: User creates comment
await createComment({ status: "pending", ... });
// → No aggregate trigger, count stays 0

// Receive hook: Relay confirms
await updateComment(repo, rkey, { status: "live" });
// → Detects pending → live transition, trigger fires, count becomes 1

Counts now reflect only what's visible to users.

This section details on the original issue you should resolve

<issue_title>Comment counts are out of sync with comment view while record is pending</issue_title>
<issue_description>Describe the bug

Comment count says 1, but no comment appears. This is because the record is pending and our aggregate rows don't take this into account.

To Reproduce

1. Revoke access to frontpage at https://bsky.social/account (this is the easiest way to get record writes to fail)
2. Make a comment

Now the post has +1 comment count but the comment doesn't show for anyone except the author.

Expected behavior

Comment count to be consistent with comment thread view.

This is pretty hard to do for both the comment author and everyone else (would require keeping track of multiple counts, or discarding our aggregate system altogether for something else). So I suggest we fix by having the count reflective of live comments only, not pending ones.

Screenshots

Additional context

The fix here involves moving the create comment trigger into the receive hook ie. after we receive the record back from the relay. We should move all triggers to the receive hook as this makes more sense architecturally.
