As an Enate user, I want a public API to manage working and non-working days in the Insights calendar so this can be automatically populated from external systems.

At the moment, there is no public API for this section, so working and non-working days must be maintained manually. This does not scale and prevents us from integrating calendars or automating the setup.

A public API available in UAT and PROD that allows us to set working and non-working days programmatically, with clear success or error feedback. This would allow us to connect enterprise calendars and keep Insights data updated automatically.
