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%.

The decisions extension tore down and re-contributed the decisions.detail
context-panel tab on every selection, racing the view's own subscription and
leaving the panel unrevealed — so clicking a decision often did nothing. Match
the working ticket panel: contribute the tab once (static), and on selection
just reveal the context panel and activateTab; DecisionDetailView loads via its
existing subscription.
