fix(inbounds): drop listen address from auto-generated inbound tag

A non-empty, non-any Address (listen) leaked into the tag as
in-<listen>:<port>-<transport> (e.g. in-127.0.0.1:443-tcp). The tag is
now always in-<port>-<transport>, with the node prefix and numeric dedup
suffix still handling uniqueness across nodes and same-port/different-listen
inbounds. Mirrored in the Go authority and the TS form preview, kept in
parity by tests.

Existing colon-form tags are now treated as custom, so editing such an
inbound preserves its tag rather than rewriting it; new inbounds (or a
cleared tag field) get the clean form.
