Fixes billing, analytics, security and legacy reference pages.
- **Operations.** `rewriteQuery`, rerank/aggregate and forget-matching each bill one operation.
- **Profile metering.** v5 profile is documented as 1 search query per call.
- **Analytics:**
- The errors response shape is fixed.
- Usage `byKey` includes `tokensUsed`, and the log `output` example has the right shape.
- The 90-day range limit doesn't exist.
- **Smaller fixes:**
- Only 2 billing endpoints need an admin.
- The `credits` response shape.
- The 2FA gate is in the feature table.
- The security page points to the one-call namespace delete for data erasure.
- Container-tag merge takes several sources.
- A stale "after API deploy" note is removed.
Checked against the current API and the published SDKs (TS 5.0.1, Python 5.0.0). Legacy v3/v4 docs are unchanged apart from factual fixes.
