The outbound HTTP SSRF blocklist did not classify NAT64
(64:ff9b::/96), 6to4 (2002::/16) or Teredo (2001:0000::/32)
addresses, whose embedded IPv4 target is invisible to the JVM
InetAddress predicates, so URLs resolving to them could reach cloud
metadata, loopback or RFC 1918 hosts from webhook delivery and media
import.
Transition ranges are now rejected outright and any embedded IPv4 is
re-checked against the full blocklist, including operator-supplied
extra blocked CIDRs.

* 🐛 Add ownership check to share-link deletion
The delete-share-link RPC command only verified file-level edit
permission but did not check if the caller owned the share-link.
This allowed any file editor to delete share-links created by
other users, disrupting collaborative workflows.
The fix adds an ownership check that allows deletion only by:
- The share-link creator (owner-id matches profile-id)
- File admins (is-admin permission)
- File owners (is-owner permission)
Implemented using TDD:
- RED: Test demonstrates IDOR vulnerability (editor can delete)
- GREEN: Ownership check prevents unauthorized deletion
- All existing tests continue to pass

The clone-file-media-object RPC command only checked edit permissions
on the destination file. The source media object was fetched directly
by UUID without verifying the caller had access to the file that owns
it.
This fix adds a read permission check on the source file before
cloning. If the caller lacks read access to the source file, the
operation fails with :not-found to avoid leaking information about
the existence of files/media the caller cannot access.

Replace the placeholder rlimit.edn with a real per-endpoint

* 🐛 Fix random backend test failure
`create-font-variant-rejects-foreign-font-id` sends `:data`, which
`schema:create-font-variant` no longer accepts: the same commit that
added the test documents that param as removed in 2.18 in favour of
`:uploads`. Both of the test's requests are therefore rejected by params
validation before they reach `check-font-team-ownership!`, which is the
thing the test exists to check. It asserted nothing about ownership and
failed three assertions.
Upload the font through `upload-font-chunked!`, the helper the other
tests in this namespace already use, and pass the session id in
`:uploads`.
`backend-tests.rpc-font-test` is 16 tests, 172 assertions, 0 failures
with this applied.

`create-font-variant` destructures `uploads` and never reads it: the
handler passes the whole `params` map to `prepare-font-data-from-uploads`.
`clj-kondo` reports it as an unused binding and exits 2, which fails the
Lint step of the Backend workflow, and the Lint step runs before the
tests, so no branch based on `develop` can run the backend suite at all.

The info-service-uri-not-configured test used config-get-mock with an
