Band Lineup 1.13.0: your own photos win, a photo dropped on someone becomes theirs, and the spots stay in reach while dragging

Photos. Sync fell back to the Planning Center headshot whenever two
library photos matched a person equally ("Mike" and "mike"), and had no
way to know "Rose" is Rosaliz — so the booth dragged those in by hand
every week. Now:
- Several equally good library photos is not a reason to use PCO's; the
  first of them is used. PCO's headshot is only for someone with no photo.
- Dropping a library photo onto the synced person already in that spot
  (same name, same first name, or a nickname sharing its first three
  letters) makes it their photo: they keep their Planning Center name and
  spot, and it is remembered (settings.json photoFor) for every later
  Sync. Photos already dragged in by hand for this plan are learned the
  same way on the next Sync.
- A synced person's library photo is read live, so replacing that photo
  updates the board without a re-sync.

Dragging. The editor was one scrolling column, so a photo found far down
the list had to be carried back up to its spot, and every drop redrew the
editor back to the top. The spots are now pinned in their own pane above
the photos, each pane auto-scrolls when a drag nears its edge, both keep
their scroll position through redraws, and a search box filters the
photos by name.
