Restructure find loop to iterate known CAMERAS+sunrise in the main shell
so cam_name is visible in the while body. Previously the for loop ran in
a process substitution subshell, making cam_name unavailable and causing
top-level year dirs (e.g. 2026/) to be treated as camera names.

Moves Season/MvtN mp4 files from flat camera dirs into
astro-YEAR/<cam>/Season/MvtN/ using season_info.py for correct
year assignment. Handles cross-year mixing in old backup structure.
Dry-run support; never deletes files.
