fix(deps): update RustSec vulnerable dependencies

[abisheik687]

Summary

Updates the vulnerable Rust dependencies reported in #6650:

• quinn-proto from 0.11.14 to 0.11.15
• tokio-postgres from 0.7.15 to 0.7.18
• required transitive postgres/crypto crates to versions compatible with tokio-postgres 0.7.18

Notes

The primary goal is to resolve the RustSec advisories for quinn-proto and tokio-postgres while keeping the change limited to Cargo.lock.

Testing

Not run locally: cargo/rustc were not available in my local environment. This should be validated by CI with cargo check/workspace checks.

Closes #6650.

The build for this fails. I get:
