Raise the declared minimums in pubspec.yaml to what our deps already
require: Flutter >=3.35.0 / Dart >=3.9.0 (was 3.19.0 / 3.5.0). alchemist
0.12 needs Flutter 3.32; Dart 3.9 first ships in Flutter 3.35, so 3.35 is
the binding floor. Pin the exact build toolchain in .fvmrc (Flutter
3.44.1).
Moving to the Dart 3.9 language level switches `dart format` to the new
"tall" style and enables two new lints. This commit is the resulting
mechanical churn, isolated from any behaviour change:
- whole-tree `dart format` reformat (tall style)
- `dart fix` for unnecessary_underscores + use_null_aware_elements
No runtime behaviour change; `make test` green.

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%.
