Feats: bruno example, gallery improvements for new scraper (#1161)

This PR bundles together two unrelated features:

1. Model Gallery improvements - specifically, the ability to follow
".ref" gallery links (which I made up for this specific application) to
an actual gallery yaml file (in order to have stable URLs) and the
ability to load self-contained configurations, rather than always using
a base.yaml + overrides. This is groundwork for my python-based
huggingface scraper.

2. A while ago I introduced some Insomnia request templates for people
to use. Unfortunately, Insomnia has decided to tank their product... So
I've personally switched to using
[bruno](https://github.com/usebruno/bruno/). Corresponding equivalent
files that I use for my testing have been added. Just open the folder
from bruno and everything will work. No import process required.
