Cardano Updates

GET /addresses/{address}/utxos returned an empty tx_hash for any UTxO whose
source block aged out of the archive window: tx_hash was built from a
block_data archive lookup, and on a miss (block_data == None, governed by
max_history) unwrap_or_default yields "". Source it from the UTxO's own
TxoRef (always present) instead.

Switches the dolos-trp dev-dependency from the rust-sdk git source (which
resolved to tx3-sdk 0.8.0 and pulled in an old tx3-tir 0.13.0) to the
published tx3-sdk 0.12.0, which no longer depends on tx3-tir. Drops the
duplicate tx3-tir from the lockfile.

`into_tx3_utxo` previously hardcoded `script: None`, so reference scripts
attached to resolved UTxOs never reached the tx3 compiler. The raw UTxO
CBOR already carries the reference script, so decode it via
`MultiEraOutput::script_ref()` and map it to `Expression::Bytes`.

The full tagged `ScriptRef` CBOR (`[tag, body]`) is preserved so the
compiler can read the script's Plutus language directly from the tag;
storing only the inner script body would drop the language tag.
