Create reusable utility for agenda folder validation

[coderabbitai]

Background

Currently, agenda folder validation logic is duplicated across different mutations. This includes checking if:

• The folder exists
• The folder belongs to the correct event
• The folder is compatible with agenda items

Proposal

Create a reusable utility function to centralize this validation logic, making the code more maintainable and reducing duplication.

This issue will need to create another common mutation function with defining the type of drizzle client only with the schema it interacts overall with all the mutations that presently has this logic. As they get the drizzle client from the context, their type is predefined.
@xoldd can you please confirm this issue once. Should I create a common one or they are better being independent.
