[CORL-3136] Fix Akismet spam/not-spam comment submissions

[nick-funk]

What does this PR do?

Update approve/reject spam submission to use FLAG__COMMENT_... for retrieving action count status instead of COMMENT_....

When we access the raw actionCounts record, we have to use the serialized values or else they will come back as undefined.

These changes will impact:

• commenters
• moderators
• admins
• developers

What changes to the GraphQL/Database Schema does this PR introduce?

None

Does this PR introduce any new environment variables or feature flags?

No

If any indexes were added, were they added to INDEXES.md?

N/A

How do I test this PR?

• run Coral in a dev mode so you can attach with a debugger
  • add a break point to server/src/core/server/stacks/approveComment.ts on line 70
    • on the submitCommentAsNotSpam call
  • add a break point to server/src/core/server/stacks/rejectComment.ts on line 132
    • on the submitCommentAsSpam call
• enable Akismet spam detection (both radio buttons on)
  • use an akismet key from one of the dev instances
• make a commenter user
• with that user, post a long comment
  • may I suggest 3-5 paragraphs of Star Trek ipsum? https://vlad-saling.github.io/star-trek-ipsum/
• edit the comment and paste in a link at the bottom of the comment
  • I used a random music video from YouTube as a URL
• see that the comment is submitted for moderation
• in the admin, see that the comment has been detected as spam
  • in the details for the marker
• approve/reject and see that the debug breakpoints you placed are hit
  • this confirms we are submitting corrections to Akismet
  • if you want to check the Akismet submission results, you can hop into those functions and debug out the results from the AkismetClient submission
    • spoiler: it's a boring and simple boolean true/false value

Were any tests migrated to React Testing Library?

No

How do we deploy this PR?

Merge into develop and then release develop into main as usual.
