A query type is introduced along with the ToQuery trait to convert types
into queries. A query can then be properly formatted as a URL query
parameter string, allowing us to pass arbitrary safely typed query
parameters to the Tera templates. This is then used by HTMX to request
the next page of content once the last row of a table is visible.
The complete separation of concerns via the gpodder repository allows us
to cleanly separate the server from the gpodder specification. This
paves the way for a later Postgres implementation of the data store.
