Adds a Colors entry under Views that buckets photos in canonical
R-O-Y-G-B-P order (plus an Uncolored tail), mirroring the rated/tags
grouping pattern. Surfaces the color label on each thumbnail as a
small swatch chip preceding the rating badge in the BL corner so
labels are visible everywhere, not just inside the new view. Also
types color_label on the Photo interface — the backend already
returned it.
