feat: add missing parameters in nano contract API

[pedroferreira1]

Acceptance Criteria

• Add before query parameter to the nano contract history API.
• Add block_hash and block_height query parameters to the nano contract state API.

Security Checklist

• Make sure you do not include new dependencies in the project unless strictly necessary and do not include dev-dependencies as production ones. More dependencies increase the possibility of one of them being hijacked and affecting us.
