cover decisions list/detail + file-tree controller to hold the floor

Wave A's widget tests pulled previously-untested files into the coverage
denominator (the decision extension loads decisions_view; the file-tree
tests load file_tree_controller), dropping total coverage to 93.6%. Add
tests for DecisionsView (list render + tap-to-select, the T-188 publisher
side), FileTreeController, and the remaining DecisionDetailView branches,
restoring the total to 95.03%.
