Camera Info gains Shutter Speed, compared in seconds and written as the
camera shows it: "≤ 1/60" finds faster exposures, "between 1/1000 and
1/125" works, and a value that isn't a time matches nothing. The editor
takes it as text (1/250, 0.5, 2").
The shutter parser moves from engine export into the catalog
(parse_shutter_seconds) so export and the rule share it. A new
rules-editor test checks that every field × operator default value
makes a valid rule.
