feat(08-01): add status column to threadCandidates and wire through backend

- Schema: status TEXT NOT NULL DEFAULT 'researching' on thread_candidates
- Zod: candidateStatusSchema enum (researching/ordered/arrived) added to createCandidateSchema
- Service: getThreadWithCandidates selects status, createCandidate sets status, updateCandidate accepts status
- Client hooks: CandidateWithCategory and CandidateResponse types include status field
- Migration generated and applied
