docs: add comprehensive parameter documentation to all API methods (#86)

Enhanced documentation for the mcrfpy module with:
- Detailed docstrings for all API methods
- Type hints in documentation (name: type format)
- Return type specifications
- Exception documentation where applicable
- Usage examples for complex methods
- Module-level documentation with overview and example code

Specific improvements:
- Audio API: Added parameter types and return values
- Scene API: Documented transition types and error conditions
- Timer API: Clarified handler signature and runtime parameter
- UI Search: Added wildcard pattern examples for findAll()
- Metrics API: Documented all dictionary keys returned

Also fixed method signatures:
- Changed METH_VARARGS to METH_NOARGS for parameterless methods
- Ensures proper Python calling conventions

Test coverage included - all documentation is accessible via Python's
__doc__ attributes and shows correctly formatted information.
