Store SQLite DB on remote host via SCP for persistence

Browse Source 
Instead of syncing JSON files back, the SQLite DB itself is now
the persistent store on the remote HAProxy host:
- Startup: download remote DB via SCP (skip migration if exists)
- After writes: upload local DB via SCP (WAL checkpoint first)
- JSON sync removed (sync_servers_json, sync_certs_json deleted)

New functions:
- ssh_ops: remote_download_file(), remote_upload_file() via SCP
- db: sync_db_to_remote(), _try_download_remote_db()
