Merge branch 'fix/home-library-card-heights' from origin

Local and remote had both advanced two commits from 3619f71 with no
overlapping files:

  remote: uniform card heights; resume after furthest-watched episode
  local:  Android native-path resume; queued watch-position sync (DR-154)

Merged cleanly with no conflicts. The series_progress policy tests pass
against the merged file (19/19).
