Reorganize docs: SQL into docs/sql/, static + pdf_rendered into docs/

Two parallel reorgs that share the same theme — keep all file-based
project assets under docs/ instead of scattered at the repo root.

User-driven moves (committed here as renames so history follows)
- static/                        → docs/static/
  Demo resumes (7 PDFs/DOCX) and demo job descriptions (4 files)
  used by tests/quality/eval_resume_parser.py and the demo job
  source. They were never served at runtime; living next to the
  rest of the project's reference assets is more discoverable.
- docs/pdf_rendered/             → docs/static/pdf_rendered/
  The two sample artifact renders (classic_resume_render.pdf,
  cover_letter_render.pdf) get folded into the same static/ tree
  alongside demo_resume / demo_job_description.

Cleanup pass — group SQL files
- docs/job_cache_cron_setup.sql        → docs/sql/job_cache_cron_setup.sql
- docs/supabase-bootstrap.sql          → docs/sql/supabase-bootstrap.sql
- docs/supabase-resume-builder.sql     → docs/sql/supabase-resume-builder.sql
- docs/supabase-saved-jobs.sql         → docs/sql/supabase-saved-jobs.sql

Path references updated
- src/config.py — STATIC_DIR moved from `BASE_DIR / "static"` to
  `BASE_DIR / "docs" / "static"`. DEMO_RESUME_DIR and
  DEMO_JOB_DESCRIPTION_DIR follow automatically. Also fixed a
  stale comment that pointed at a `docs/supabase-resume-builder
  -ttl.sql` file that doesn't exist (the real file is the
  resume-builder migration, now under `docs/sql/`).
- docs/architecture.md — cron-setup link now points to
  `docs/sql/job_cache_cron_setup.sql`.
- docs/adr/ADR-013 — same link updated.
- tests/quality/eval_resume_parser.py — argparse help text
  references `docs/static/demo_resume` (was `static/demo_resume`).

DEVLOG.md still has historical references to the old paths;
those are kept as-is since the day-by-day log records what
locations were in play at the time the work shipped.
