## Summary
- New **Back office** tab at `/admin`, per-org detail page at
`/admin/back-office/orgs/:orgId` designed to host future per-org admin
actions (project count, delete account, YC deals).
- First action: edit an organization's API rate limit — tokenBucket
override (refill rate, interval, max tokens), with a live plain-English
preview (e.g. *"1,500 requests per minute · 750 request burst
allowance"*). Writes are audit-logged via the server logger.
- Cleanup: removed unused `v2?` / `v3?` columns from the admin orgs list
(display only — Prisma select untouched).
## Test plan
- [ ] Back office tab visible in admin nav and highlighted when on a
sub-route
- [ ] `/admin/orgs` shows a Back office "Open" link per row; no v2/v3
columns
- [ ] Empty state at `/admin/back-office` links back to `/admin/orgs`
- [ ] Detail page renders the effective rate limit in view mode; Edit
reveals the form
- [ ] Save writes `Organization.apiRateLimiterConfig`, returns to view
mode, shows "Rate limit saved." banner
- [ ] Invalid values surface inline field errors and keep edit mode
- [ ] Non-admins hitting any new route are redirected to `/`
- [ ] Server logs show `admin.backOffice.rateLimit` info line per
mutation
