Modernize frontend with tabs, HTMX, and Tailwind build pipeline

Complete UI overhaul implementing modern design patterns with HTMX for
dynamic updates, proper Tailwind build pipeline, and improved UX.

Build Pipeline:
- Add npm + PostCSS + Tailwind CSS configuration
- Custom design system with brand colors
- Compiled CSS: 27KB (vs 3MB CDN), 99% reduction
- Makefile for unified build commands
- Inter font for improved typography

Tab Interface:
- Separate Tasks tab from Notes tab using HTMX
- Partial page updates without full refreshes
- Tab state management with proper refresh handling
- New endpoints: /tabs/tasks, /tabs/notes, /tabs/refresh

Template Architecture:
- Modular partials system (7 reusable components)
- Cleaner separation of concerns

Empty Board Management:
- Active boards in main 3-column grid
- Empty boards in collapsible section
- Reduces visual clutter

Visual Design Enhancements:
- Inter font, brand color accents
- Improved typography hierarchy and spacing
- Enhanced card styling with hover effects
