feat: add card in Pages and Resources to allow hiding the dates tab

[Anas12091101]

Description

This PR adds a Date Course App to the Pages and Resources API, enabling course authors to hide the Dates tab from learners using the authoring MFE. The app is behind a feature flag and will only be displayed when the FEATURES["ENABLE_DATES_COURSE_APP"] is set to True.

Useful information to include:

• Which edX user roles will this change impact? Common user roles are "Learner", "Course Author".
• Include screenshots for changes to the UI (ideally, both "before" and "after" screenshots, if applicable).
