refactor(aws-ps-integration): make `AWS Parameter Store` integration easier to use

[GLEF1X]

Description 📣

This pull request refactors the AWS Parameter Store integration UI to enhance the user experience and improve code maintainability. The changes introduce a new IntegrationAuth component and update the form handling process.

Issues Fixed

• Improves form validation and error handling for AWS Parameter Store integration setup.
• Resolves an issue where incomplete form validation allowed submission of incomplete data, resulting in database constraint violations(see video for more details).
• Allows user to deselect AWS KMS key after selecting one.

Other Improvements

• The autoFocus attribute is now applied to the initial input fields in the form's DOM structure. Specifically, the environment and accessId fields are set to automatically receive focus when the form loads.
• Enhances code reusability with the new IntegrationAuth and IntegrationCreate components. This will allow to create or refactor integrations faster.

Type ✨

• [x] Bug fix
• [x] Refactoring
