ubc: sync module_A and module_C cards, module_A pipeline and figures with GitHub

Syncs the two ubc module cards, the module_A pipeline and the figures on the Hub with the reviewed state on GitHub (open-h/OpenH-RF).

`module_A/pipeline.yaml` gains `scan_convert` and the parameters it needs. The 64 transmits span +/-1.088 rad, while the probe's stored `polar_limits` (+/-1.4144 rad) describe its full field of view, so scan-converting against the stored limits produces a sector wider than the one actually acquired; `polar_limits` and a 0.4 mm `resolution` are now set explicitly. The comment on `zlims` also records that zea reads `distance_to_apex` (10 mm) from the file and adds it to form `rho_range`.

Adds the example reconstruction each card now shows, `module_A/assets/module_A.png` and `module_C/assets/module_C.png`. The four remaining files are the reference outputs that produced them — a frame and a 25-frame loop for module_A, a scan-converted frame for module_C — plus `module_C/assets/main.png`, the release image. None of those four are embedded in the cards.

Both cards also get the same contributor list, in the same order, which they previously stated differently.

Files changed: 9.
