feat: add Security Patch Applier — 5.7

Add automated script that detects security updates, creates a branch,
updates requirements.txt, runs tests, and opens a PR via Gitea API.

Acceptance:
- Detects security update (via `pip list --outdated`)
- Creates branch (step35/security/patch-<pkg>-<ver>)
- Updates dependency (requirements.txt)
- Runs tests (pytest)
- Opens PR (Gitea API, Closes #113)

Resolves: #113
Task: 5.7 — Security Patch Applier
