Implement `Arbitrary` for psbt types

This commit adds optional support for the `arbitrary` crate, a Rust fuzz-testing helper, across several data types in the rust-bitcoin library. It does not change normal runtime behavior; the new code is only compiled when the optional `ar…

Unchecked index into `Vec` replaced with bounds-checked `get`Panic-to-error conversion in transaction signing codeRegression test added for malformed/missing UTXO data
