RELIC: Add serverpod_lints to the Framework

[klkucaj]

Is your feature request related to a problem? Please describe.
The framework currently does not enforce consistent coding standards, which can lead to discrepancies in code quality and style. Adding serverpod_lints will help maintain uniformity and improve the overall quality of the codebase.

Describe the solution you'd like
Integrate serverpod_lints into the framework to:

• Enforce consistent coding conventions and best practices.
• Catch common mistakes and potential issues during development.
• Ensure alignment with the style and standards recommended by Serverpod.

Describe alternatives you've considered

• Using package:lints or other general-purpose linting packages. While helpful, they do not provide the specific rules and conventions tailored for Serverpod.

Additional context
Adding serverpod_lints will streamline development, reduce code review overhead, and ensure the framework adheres to a standardized style guide. This will also make it easier for contributors to follow the same coding practices.
