feat(wasteland): add Claims page with listClaims procedure and ClaimsClient

[jrf0110]

Summary

• Add listClaims tRPC procedure that filters browseWantedBoard results to claimed items, supports optional rigHandle server-side filter, and enriches each claim with pending PR information from DoltHub open pulls (kind: claim/done/unclaim)
• Replace the 5-line ClaimsClient stub with a full claims overview page including: page header with count badge and refresh, filter bar (search, rig handle dropdown, pending PR toggle, sort cycling), stats strip (total/pending PR/stale claims), claims table with status dots, item ID, title, priority/type chips, claimed-by links, time-ago labels, pending PR badges, and kebab menus, plus empty state with CTA, loading skeleton, and error state with retry
• Extract shared STATUS_COLORS, STATUS_DOT, PRIORITY_COLORS, TYPE_COLORS constants to apps/web/src/lib/wasteland/status-colors.ts
• Update frontend type declarations (router.d.ts) with listClaims procedure output types
• Add PendingPrOutput and ClaimRowOutput Zod schemas to backend schemas

Verification

• pnpm --filter web typecheck passes
• pnpm --filter web lint passes
• pnpm --filter cloudflare-wasteland typecheck passes
• pnpm --filter cloudflare-wasteland lint passes
• pnpm format applied

Visual Changes

N/A — new page, no before/after

Reviewer Notes

• The listClaims procedure calls browseWantedBoard internally then filters, which means two loadContext calls (one in browse, one for PR enrichment). This is acceptable for now — the credential is cached in the DO.
• PR kind determination uses parseCommitSubject on the PR title. If the title doesn't match the wl commit subject pattern, it defaults to "claim" which is the most common case.
• Force unclaim in the kebab menu currently shows a toast placeholder — the actual mutation will be added in the follow-up bead (84c6229b).

Code Review Summary

Status: No Issues Found | Recommendation: Merge

All 3 issues flagged in the previous review have been resolved in the follow-up commit:

• ✅ Toast leak on unmount — cleanup now dismisses any already-shown toast
• ✅ claimed_by null → /rigs/null — Link is now conditionally rendered, with an "unclaimed" fallback span
• ✅ Empty string in claimedItemIds — .filter(Boolean) added to exclude empty fallbacks
