Greasy Fork镜像

Added last main refresh timestamp text back (missed it when I fixed the bug for non-premium users)

Fixed script for non-premium users

The script should only run on the main Kadaotery page. Otherwise it incorrectly marks an attempted feeding (successful or not) as a refresh time, resetting the timestamp and moving it to later than the actual refresh time.

More bug fixes

Attempting a bug fix (but tis hard, folks) for a reported issue I cannot reproduce

Fixed bugs around expired time windows or initial state (when we don't have a window input yet).
