- Rate limit the import check probe and refuse private, loopback, and
link-local targets on Cloud.
- Rate limit the SSH validation that an import starts, like other
server validations.
- Count only managed servers for the server limit, the limit check job,
and the subscription page. Archives of transferred servers are left out.
- Do not show the name of another team's archived server in the import check.

Update server limit enforcement to re-enable force-disabled servers when the
team is at or under its limit (`<= 0` condition).
Improve allowlist validation and matching by:
- supporting IPv6 CIDR mask ranges up to `/128`
- adding IPv6-aware CIDR matching in `checkIPAgainstAllowlist`
- normalizing/deduplicating redundant allowlist entries before saving
Add feature tests for `ServerLimitCheckJob` covering under-limit, at-limit,
over-limit, and no-op scenarios.
