This commit adds and improves numpydoc-style docstrings to the quantlib/time/date.pyx and quantlib/time/calendar.pyx files.

The following classes and their methods have been documented:
- `Period`
- `Date`
- `Calendar`

The docstrings now use fully qualified type hints to support documentation generation and cross-referencing. The `Parameters` sections have been moved to the class docstrings for consistency.

Additionally, a bug in the `is_end_of_month` method in `quantlib/time/calendar.pyx` has been corrected.
