feat: Standardize Database and L2 Calls

[eduramme]

Currently, the database and Layer 2 (L2) calls do not follow a consistent standard. This can lead to difficulties in maintaining and reading the code, as well as potential performance and scalability issues.

Describe Preferred Solution

• Analyze the current database and L2 calls to identify inconsistencies and areas for improvement.
• Define a standard for database and L2 calls that is efficient and maintainable.
• Refactor existing calls to adhere to the new standard.
• Document best practices for database and L2 calls in the project to ensure that new developments follow the established guidelines.

QA Notes:

• [x] DB subdomain register
• [ ] Arb subdomain register
  • still ask for adding the Arbitrum Sepolia on the Metamask when it already has
  • I'm unable to register a subdomain on the L2
