refactor: profile import optimisation (#165)

feat: add concurrent, async requests to improve profile / format import performance

feat: optimise cf prefetching, reduce verbose logging
- now only make single request, then propagate changes to remaining profiles
- remove verbose logging

fix: increase Gunicorn worker timeout to 10 minutes to prevent timeouts during database syncing operations
