[Feat] announcements end-to-end flow

[davidlhw]

Features

Currently, the announcement banners (3x red cards/boxes) are using placeholder cards that dont have any functional utility. This task focuses on implementing that.

Core

• New DB table announcements
  • link string field - for the url of the announcement
  • external bool field - to declare if this announcement's link is external or not
  • image string field - for the url of the image used in the background
  • createdAt field - refer to other tables
  • updatedAt field - refer to other tables
• Read from db table and populate information on the card (thi component should be a server component)

Optional

• styles
  • make announcement banner responsive (scroll on overflow in x-axis or use a carousel)
