## What this changes
Cleaning up the portal home page. Most of what was under the plan card
was mock — it hit endpoints that don't exist on any backend, so on SaaS
it just showed a wall of "—" and "Nothing here yet". I removed the fake
stuff and wired the bits worth keeping to real data.
**Scrapped (all mock, no backend anywhere — self-hosted included):**
- The "No usage yet" usage chart
- The KPI strip (Docs/30d, Pipelines, Agents active, Eval pass rate)
- The "Build a pipeline in seconds" fork wizard (fake build animation,
deploy was a TODO)
- The Sources/Pipelines/Agents product cards
- The "Popular use cases" marketing cards
- Enterprise region health
- The "Try a PDF operation" runner
Deleted their component/api/mock/MSW/story files too, plus the now-dead
i18n keys and CSS.
**Wired to real data (finished, not removed):**
- The plan strip and the sidebar footer now show the **real** 30-day
processed-PDF count from `/api/v1/usage/fleet-stats` (was a mock KPI).
Shows "—" honestly when the backend can't compute it, never a fake
number.
- **Recent activity** now reads the **real audit log** — the same
endpoint the Infrastructure → Audit tab uses.
**Result:** one simple layout for all tiers — plan strip → recent
activity + quick actions → "What runs on your PDFs" (the real policy
summary). Every block is backed by data that actually exists.
Net: **−3,221 / +89 lines**, 17 files removed.
## Testing
typecheck (all variants), full test suite (1211), saas + proprietary
builds, lint, format, storybook build, toml-sort — all green. The
`unusedTranslations` test guarantees no orphaned i18n keys were left
behind.
