Projection plotting fails for supported angle inputs: animation indexes one-dimensional angles as a two-dimensional array, and static views cannot format three-component ZYZ angles correctly. Lowercase dim="t" also misses animation setup, and detector U/V slices can incorrectly index the view-angle array.

Normalize and validate (views,), (views, 1) and (views, 3) angle arrays, display the first angle component only for projection views, and retain the animation on the plot object. Preserve plotSinogram and empty-GIF-filename behavior.

Validation: 22 CPU/Agg tests cover static slices, first/last animation frames, angle shapes, invalid inputs and empty GIF filenames. Upstream aea5346 has 16 failures and 6 passes; all 22 pass with the fix. The tests load the plotting module directly and require no compiled TIGRE extensions.
