feat(resources): client-side search

[chrismclarke]

Is your feature request related to a problem? Please describe.
As the list of resources available within the app continues to grow, finding specific resources (which are often nested in collections and sub-collections) becomes harder to do. It would be nice to have an interactive way to search for specific resources

https://picsa.app/resources

Describe the solution you'd like

• Integrate FuseJS to support client-side search of data
• Create a new resources/search page that includes a search box and displays lists of results from all resources

Additional context

• The existing resources service provides access to resources grouped by type (e.g. collections, files and links). Ideally the search engine should be able to search across all of these
• Search should include multiple properties in resource objects, with higher weights given to title (50%), description (30%) and perhaps filename/url the final (20%)
