Show full error response from accounts manager, increase timeout

- Remove -f from curl so HTTP error responses are visible
  (was silently swallowing non-200 responses as empty)
- Increase retry to 60 attempts / 5 min (accounts-manager needs
  time to import and unlock accounts via the daemon)
- Increase job timeout to 20 min
