feat(faucet): add new paginated GraphQL queries for transfers

[PablitoAmaral]

This PR updates the SQL insert statement to use datetime('now') for the time column instead of TIME(). It also adds new GraphQL queries to enhance the faucet functionality and introduces a maximum limit for paginated calls to improve security and performance.

SQL Insert Statement Update:
Changed the SQL insert to use datetime('now') for better timestamp handling.

New GraphQL Queries:
Unhandled Transfers: Get all unhandled transfers with pagination
Handled Transfers: Get all handled transfers with pagination
Transfers for a Specific Address: Get all transfers for a specific address with pagination

Looks good to me, except for the paginated calls we should have a max, ideally set with a cli arg. That way, if we ever get DOSed, we can in the cli set the number to 50 or something.
