fix(tests): improve libtmux.test.waiter test coverage and fix issues

WHAT:
- Fixed type annotations for regex pattern lists in test_wait_for_all_content_regex_match
- Removed duplicate test_wait_for_all_content_regex_match function
- Added proper mocking for exception handling tests by correctly patching
  retry_until_extended instead of a non-existent _retry_until_extended function
- Added type annotations to all mock functions
- Improved test implementations to correctly simulate exceptions

WHY:
- To ensure type safety and fix mypy errors that were preventing tests from passing
- To eliminate duplicate code that was causing redefinition errors
- To properly test error handling paths in waiter functions
- To improve code quality and maintainability through correct type annotations
- To achieve more comprehensive test coverage for edge cases and exception paths

The changes ensure all 60 tests now pass successfully, providing better
coverage of the waiter module's functionality, particularly for error
handling paths and edge cases.
