- refactor Contacts page: convert updateContact mutation to object syntax
- refactor Expenses page: convert createExpense, updateExpense and deleteExpense mutations to object syntax
- refactor Files page: convert createFile and updateFile mutations to object syntax
- add explicit mutationFn property for better code clarity and maintainability
