Re-add --pprof-bind-address and --webhook-bind-address flags

Re-adds the pprof endpoint flag (default: disabled) and webhook port
flag (default: 9443) that were previously removed.

These flags are required for local development scenarios and avoiding
port conflicts when running multiple operators.
