* upgrade axum to 0.8.9 (and side deps)

Bumps axum 0.7.5 → 0.8.9, axum-extra 0.9.4 → 0.12.6,
axum-client-ip 0.6.1 → 1.3.1, axum-test 16.2.0 → 20.0.0,
utoipa-swagger-ui 8.1 → 9.0.2.

* warn upon using fallback ip

Co-authored-by: coderabbitai[bot] <136622811+coderabbitai[bot]@users.noreply.github.com>

* chore: replace use of deprecated try_next()

* update console-subscriber to ensure single version of axum in the lock file

* removed unused axum-test dev-dep
