Good first steps, thank you!

Please see my comments + you have compilation errors/warnings, so the CI is not passing yet.

@ggwpez Hi Oliver ! Would you know if this line can be safely removed ? idk if it has any side effects on tests but it doesnt seem to do at first glance https://github.com/paritytech/polkadot-sdk/blame/master/substrate/frame/paged-list/src/paged_list.rs#L448

Cannot be removed, see its drop.
It is equivalent to wrapping everything below into an assert_storage_noop! to ensure that there are no undue storage changes happening.

Good minus the one comment 😄

I added all traits that were not used by multiple pallets to the umbrella crate and integrated the defensive! macro changes following the merge of #7069
