Add curl fallback for KİK document retrieval

Python SSL libraries (httpx, requests, urllib) fail with SSL handshake
errors against ekap.kik.gov.tr legacy server. curl uses different SSL
implementation (LibreSSL) that works.

Changes:
- Add subprocess + shutil imports
- Replace httpx fallback with curl fallback in get_document_markdown
- curl uses -k (insecure), -s (silent), -L (follow redirects) flags
- Enables KİK document retrieval on FastMCP Cloud without Playwright
