fix(docs): correct EAS variable naming and attestation UID access (#652)

- Fix variable naming conflict (const EAS = new EAS -> const eas = new
EAS)
- Fix attestation UID access (receipt.attestationUID ->
newAttestationUID from tx.wait())
- Apply fixes to all 4 EAS documentation files for consistency
- Ensures code examples work correctly when copied by developers
