This upgrades the `proxy/` crate as well as the forked libraries in `libs/proxy/` to edition 2024. Also reformats the imports of those forked libraries via: ``` cargo +nightly fmt -p proxy -p postgres-protocol2 -p postgres-types2 -p tokio-postgres2 -- -l --config imports_granularity=Module,group_imports=StdExternalCrate,reorder_imports=true ``` It can be read commit-by-commit: the first commit has no formatting changes, only changes to accomodate the new edition. Part of #10918
