DC-003: Move stale debug test scripts to scripts/legacy/

comprehensive-test.js and test-security-fixes.js are 875 lines of
ad-hoc security test scripts (not Jest tests). They have zero references
in code or docs. Moved to scripts/legacy/ to declutter repo root
without losing the content. All 759 Jest tests still pass.

 - **result:** Fixed root VERSION to 1.13.4. Updated `scripts/release.sh` to write both `dashcaddy-api/package.json` AND root `VERSION` on every release — also stages VERSION in the release commit. No more drift.

 - **details:** `comprehensive-test.js` and `test-security-fixes.js` are ad-hoc test scripts, not Jest tests. They clutter the repo root. Remove them or convert to proper Jest tests under `__tests__/`.
+- **result:** Moved both files to `dashcaddy-api/scripts/legacy/` (preserved, not deleted — they are 875 lines of security test coverage that may be useful as a manual smoke test). Zero references to them in code/docs — safe to move. All 759 Jest tests still pass.
