feat(programmer): admin monitor tab + drill-down

- Add isStrictAdminProvider (role == 'admin' only)
- Add programmer_tasks_tabs.dart with ProgrammerTasksTab enum,
  programmerTasksTabsFor, parseProgrammerTasksTab, programmerTasksTabLabel
- Make ProgrammerTasksListScreen role-aware via initialTab param and
  programmerTasksTabsFor; admin sees Monitor/Mine/All tabs
- Add MonitorTab with AppStatusSummaryRow + responsive programmer grid
  (1/2/3 cols) + HelpPanel side/bottom
- Add ProgrammerMonitorCard with state pills (Working/Paused/Idle/On leave/Pass slip)
- Add HelpPanel ConsumerStatefulWidget with day stepper and help-edge rows
- Add ProgrammerDrillDownScreen (/programmer-tasks/programmers/:userId);
  non-admins see lock empty view
- Router: pass tab query param; add programmers/:userId before :id route
- Tests: 7/7 pass; analyze: 0 new issues
