fix(lightroom): content duplicates start from import defaults; Show in Library skips Recently Deleted (#2589)

A catalog photo whose bytes match another library photo got the generic develop defaults, so a raw
with no white balance or lens setting in the catalog lost its as-shot white balance and embedded
lens corrections and rendered unlike a file import. It now gets the import defaults (camera
defaults plus the default preset), as a file import does, before the catalog's settings go on top.

Show in Library selected the lowest mapped photo id, which can be a master left in Recently Deleted
whose new virtual copy the import added; All Photos doesn't show it. It now selects the lowest
mapped photo not in Recently Deleted, and the button is left out when there is none.

Tests: a content-duplicate raw with no catalog settings equals its camera defaults (as-shot WB,
lens profile on); Show in Library skips a trashed mapped photo and offers nothing when only
trashed or vanished ids are mapped.
