Allow ranges to be specified (instead of a comma-separated list format) for annotations such as "traffic.kuma.io/exclude-inbound-ports" or anything that uses numbers as a value

We would like to specify ranges of port numbers (such as 2000-4000) instead of having to list each port individually in a comma-separated list. Right now it appears this only allows for a single port number or else a comma-separated list of ports but no ranges appear to be included.

We may have a very large list of ports (i.e. 2000 ports) they need to exclude and of course do not want to have to write all of them individually if they're a contiguous range of numbers such as ports 4000-6000. When there's only a few ports it's easy enough to do as-is, but for larger ranges this becomes troublesome as it requires using other tools like online number generators or AI tools to generate such a list in the expected format.

This feature request should apply to any annotations that specify numbers as values, but specifically these to be included:

• traffic.kuma.io/exclude-inbound-ports

• traffic.kuma.io/exclude-outbound-ports
