Improve type error messages to show types instead of values

[jpfeuffer]

• Modified assertion error messages to include expected Python type
• Changed overload error to show argument types instead of values
• Added function name to overload error messages for better context

Example improvements:

• Before: 'arg my_arg wrong type'

• After: 'arg my_arg wrong type (expected list[int])'

• Before: 'can not handle type of (value1, value2)'

• After: 'can not handle types (str, list) as arguments for function myFunc()'
