Add a Program content type and render the programmes page from the programs view

Problem/Motivation

The programmes we run are the core of the site, but there is no Program content type. The Our Programs page hand-builds five programme blocks out of Canvas components, so a site builder cannot add a programme, a programme cannot be listed or filtered, and nothing can reference one.

Steps to reproduce

1. Install the Horizon Aid site template.
2. Open /admin/content and try to add a programme: there is no Program content type.
3. Open /programs: five hand-placed blocks, each about sixty Canvas components in total.

Proposed resolution

Add a Program content type the way Varbase Blog Base manages a content type, following the same structure as the Program type in the Educare site template, adapted for an aid organisation.

• Content type program with a summary, content, featured image, a Sector reference to a new program_type vocabulary, and a Countries reference to the Country content type, so a programme states where it runs.
• Form display, a card view display and its Drupal Canvas content template.
• A programs view with block displays for the listing, rendered through the card view mode, and a pathauto pattern so a programme lives at /programs/[node:title].
• Replace the hand-placed blocks on the Our Programs page with the view.
• Five programmes carrying the copy and images already on the page: Education, Women, Agriculture, Medicine and Health, each linked to the countries where it runs.
