ERH Resource Catalog - Githubissues

As a user accessing the ERH, I want to be able to browse and search a catalog of available resources.

Resources should be loaded and cached from Airtable, building on #112.
Resources should be organized by actionable categories, like "Gather election data" or "Engage with experts".
Resources should be searchable. Search results are displayed as an uncategorized grid of resources.
Resources should link to dedicated pages containing more details and an "access" button: #119
