chore(`cargo deny`): migrate away from `number_prefix`

[zerosnacks]

We've currently marked it as ignore in our cargo deny

foundry/deny.toml

Lines 12 to 13 in 828c8c9

	# https://rustsec.org/advisories/RUSTSEC-2025-0119 number_prefix! is unmaintained
	"RUSTSEC-2025-0119",

Following this reasoning

No direct action required, imo prefer keeping the old crate versus introducing a new recommended: https://crates.io/crates/unit-prefix considering we have a number of dependencies that still rely on number_prefix, some of them being soldeer / cliclack and ui_test (https://github.com/oli-obk/ui_test/blob/67eccdb99d9956af7b0a6620fee75dd61a9a5794/Cargo.toml#L26)

Once upstream changes are passed we can migrate away
