feat(auth): add POST /login with Playwright automation and SQLite session storage

- automates file-key login on the ID portal using Playwright/Chromium
- captures token, cookies, and localStorage after successful redirect
- stores session data in SQLite via TypeORM (better-sqlite3)
- sessions are keyed by sessionName (auto-generated UUID if not provided)
- login URL, cabinet redirect URL, keys dir, and DB path are all configurable via env
