Add web GUI: FastAPI API + Vue 3 frontend with dark theme

API (web/api.py):
  GET  /api/projects, /api/projects/{id}, /api/tasks/{id}
  GET  /api/decisions?project=X, /api/cost?days=7, /api/support/tickets
  POST /api/projects, /api/tasks, /api/decisions, /api/bootstrap
  CORS for localhost:5173, all queries via models.py

Frontend (web/frontend/):
  Vue 3 + TypeScript + Vite + Tailwind CSS v3
  Dashboard: project cards with task counters, cost, status badges
  ProjectView: tabs for Tasks/Decisions/Modules with filters
  Modals: Add Project, Add Task, Add Decision, Bootstrap
  Dark theme, monospace font, minimal clean design

Startup:
  API:  cd web && uvicorn api:app --reload --port 8420
  Web:  cd web/frontend && npm install && npm run dev
