chore: harden OpenSSF Scorecard from 4.3 to ~7.0 (#142)

Token-Permissions (0 -> 10): Set permissions: {} at workflow top level
across all 7 workflows, moved write scopes to per-job minimum.

SAST (0 -> 10): Added CodeQL workflow for JavaScript/TypeScript and
Python analysis on push, PR, and weekly schedule.

Vulnerabilities (0 -> ~8): Added 13 pnpm overrides to patch transitive
dependency vulnerabilities (38 -> 2 remaining, both in dev-only tools).

Pinned-Dependencies (5 -> 8-9): Pinned all Docker FROM images to SHA
digests, pinned pip-audit version in CI, pinned pip version in
Dockerfile.
