chore: release v8.0.3 - fix Seaport initialization for custom chain deployments (#1794)

* fix: pass correct Seaport contract address during initialization

- Add getSeaportAddress import to SDK initialization
- Pass contractAddress in Seaport overrides config
- Ensures chains like Somnia use correct Seaport address (Gunzilla Seaport)
- Fixes "could not decode result data" error when calling getCounter

Previously, the SDK was creating Seaport instances without specifying the
contract address, causing seaport-js to default to the cross-chain Seaport
address. This resulted in errors on chains like Somnia that use custom
Seaport deployments (Gunzilla Seaport).
