Walkthrough

CalendarMonth now accepts OUIA props, renders the corresponding data-ouia-* attributes, includes integration tests, and is listed in the OUIA developer guide.

Layer / File(s)	Summary
OUIA props and root rendering packages/react-core/src/components/CalendarMonth/CalendarMonth.tsx	CalendarMonth accepts ouiaId and ouiaSafe, computes OUIA props, and applies them to its root element.
OUIA validation and documentation packages/react-core/src/components/CalendarMonth/__tests__/CalendarMonth.test.tsx, packages/react-core/src/helpers/OUIA/OUIA.md	Tests verify generated OUIA attributes, defaults, overrides, and snapshot output, and the guide lists CalendarMonth as supported.
