Update the rusqlite and arti-client crates

[str4d]

This was previously blocked on schemer, because we cannot have two different versions of the libsqlite3-sys crate in our dependency tree. After switching to schemerz in #1575, we can now update these in sync.

[str4d]

I checked and I believe our constraints here are met for all rusqlite versions existing in this PR:

rusqlite	Bundled SQLite	Matching CocoaPods sqlite3 tag
0.29	3.41.2	✅
0.30	3.44.0	✅
0.31	3.45.1	✅
0.32	3.46.0	✅

[str4d]

Force-pushed to back out rusqlite 0.32 from this PR. It requires MSRV 1.77, which I think would be reasonable, but not in this PR (I'd make a separate PR for that, once we've determined that getting as far as rusqlite 0.31 is fine).

[str4d]

cargo vet will fail because I haven't updated the audits for the dependency changes. I'll force-push with those changes later.

Rebased on main to fix merge conflicts, and fixed lints.

utACK 8ff0b1a - it's really nice to see all that reduction in duplicated dependencies!

Love to see those deduplications of crypto crates <3. Post-hoc ACK.
