feat: add resume library and per-job resume API endpoints

- POST/GET /api/resumes — create and list resumes
- POST /api/resumes/import — import from .txt/.pdf/.docx/.odt/.yaml
- GET/PATCH/DELETE /api/resumes/{id} — CRUD for individual resumes
- POST /api/resumes/{id}/set-default — set default resume
- GET/PATCH /api/jobs/{job_id}/resume — per-job resume association
- Extend approve_resume to optionally save to resume library (save_to_library + resume_name body fields)
