fix: convert remaining let-chains to nested ifs for MSRV compat

Refactor four let-chain patterns (`if let ... && ...`) in
process_approval() to use nested `if`/`if let` blocks. Let-chains
require `#![feature(let_chains)]` which is not available on our MSRV.
Add `#[allow(clippy::collapsible_if)]` with a comment explaining why.
