feat(wasteland): add Claims page tRPC tests + docs

[jrf0110]

Summary

Add tRPC procedure tests and documentation for the Claims page.

Tests (services/wasteland/src/trpc/router.test.ts):

• listClaims with rigHandle filter
• listClaims returns only claimed items
• listClaims returns pending_pr with correct kind (claim/done) when DoltHub has matching open PRs
• listClaims returns empty array when DoltHub enrichment fails (PRECONDITION_FAILED)
• listClaims sets pending_pr to null when credential loading fails
• forceUnclaimWantedItem rejects empty/whitespace-only reason (Zod validation)
• forceUnclaimWantedItem rejects itemId with invalid characters (Zod regex)
• forceUnclaimWantedItem requires upstream admin (FORBIDDEN when isUpstreamAdmin=false)

Component tests: Skipped — no *.test.tsx pattern exists in the wasteland app area (project doesn't do RTL component tests there).

Playwright e2e: Skipped — existing e2e tests require a running app with full auth; can't meaningfully test claims page without full wasteland infrastructure.

Docs (services/wasteland/docs/admin-mode.md):

• Added "Claims page" section covering what the page shows, force unclaim workflow and audit trail, and how pending_pr enrichment works with in-flight DoltHub PRs.

Infra (services/wasteland/src/trpc/init.ts):

• Exported createCallerFactory from the tRPC instance for test use.

Verification

• pnpm --filter cloudflare-wasteland test passes (22/22 tests)

Reviewer Notes

The test file uses vi.mock to stub DO stubs, DoltHub API, and crypto helpers — necessary because the router procedures depend on Cloudflare Durable Object bindings and external DoltHub API calls that can't run in a Node test environment.
