Fix: disable SSL verification for edited media server upload

Root cause identified from logs:
  [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self-signed certificate

The server uses a self-signed certificate (like production), but the edited media
upload endpoint was not disabling SSL verification while other API calls do.

Solution:
- Add verify=False to requests.post() call in _upload_to_server()
- Matches the SSL verification handling in get_playlists_v2.py
- Add warning about SSL verification being disabled
- Now edited images can upload successfully to server

This fixes the upload failures that were preventing edited images from being
synced to the server.
