- app.dart: add braces to single-statement if body
- briefing_api.dart: escape <id> in doc comment (unintended HTML)
- notes_api.dart, tasks_api.dart, projects_api.dart: use null-aware
map elements (?'key': value) instead of if-null guards
- task_edit_screen.dart: remove unused tasks_api.dart import
- task_edit_screen.dart, project_selector.dart: suppress
deprecated_member_use on DropdownButtonFormField.value (value is
the controlled-widget param; switching to initialValue would break
current-selection display)
- project_selector.dart: use _ instead of __ for ignored error params
