Credit activity ledger: every earn and spend logged with a reason, listed under Campaigns

Hugh earned a 10-credit sign-in bonus, then bought a 280-credit extension; earned credits spend
first, so Earned read 0 and the bonus looked lost. There was no record a member could check.
Now every real credit movement writes a credit_log row (JSON store in file mode): welcome, sign-in
bonus with streak, daily claim, inbox reads, video watches, verified visits, milestone/leaderboard
bonuses, partner codes, admin/team grants, AI Copy Engine charges + refunds, flat buys (featured
run, extension, visit pack, more visits), login-ad days, and metered delivery rolled up per
campaign per day; on-chain purchased-credit spends are marked. GET /api/my/credits/activity;
dashboard shows the last 40 under Campaigns (also when there are no campaigns) with a link from
Earn credits. Chatbot canned answer + AI prompt updated; my.js tag bumped.
