The phash_threshold knob (controls whether edits/variants of an image are
dropped as near-duplicates on import) was buried at the bottom of the import
filters form and labelled opaquely, so it read as 'missing'. Hoist it to the
TOP of the form as a 'Near-duplicate sensitivity' section: a labelled slider
(Exact / Strict / Default / Loose stops, 0-16) for the gist + the precise
number field, both bound to phash_threshold, with copy that says plainly to
lower it if variants are being dropped.
Also swap the import-tab order to filters → trigger → recent-tasks (filters on
top per operator); the task list stays directly under the trigger for hit/miss
feedback adjacency.
