feat: return variable value if it is a generic variable (#5366)

* fix: update pre-commit configuration for ruff formatting args

* fix: update variable type constant from GENERIC_TYPE to CREDENTIAL_TYPE

* feat: enhance variable service to handle decryption for generic type and update default variable type to CREDENTIAL_TYPE

* feat: add abstract method to retrieve all variables for a user in VariableService

* feat: implement get_all method in KubernetesSecretService to retrieve and decrypt user variables

* refactor: update variable tests to use fixtures for generic and credential types

- Renamed and refactored test fixtures for better clarity and reusability.
- Updated tests to utilize `generic_variable` and `credential_variable` fixtures instead of hardcoded values.
- Enhanced assertions to ensure correct handling of variable types, including encryption for credential variables and decryption for generic variables.
- Improved test structure for creating, reading, updating, and deleting variables, ensuring consistency across test cases.

* refactor: update get_all method signatures in variable services to return VariableRead

- Changed return type of the get_all method in VariableService, KubernetesSecretService, and DatabaseVariableService from list[Variable | None] to list[VariableRead].
- This update enhances type consistency across variable services and aligns with the new VariableRead model for improved data handling.

* fix: update variable type assertion in test_update_variable to CREDENTIAL_TYPE

- Changed the assertion in the `test_update_variable` test to verify that the result type is now `CREDENTIAL_TYPE` instead of `GENERIC_TYPE`.
- This update aligns the test with recent changes in variable type handling, ensuring accurate validation of variable updates.

* fix: update variable type assertion in test_create_variable to CREDENTIAL_TYPE

- Changed the assertion in the `test_create_variable` test to verify that the result type is now `CREDENTIAL_TYPE` instead of `GENERIC_TYPE`.
- This update ensures consistency with recent changes in variable type handling and improves the accuracy of the test validation.
