feat: Sprint 1 — Alive Enterprise animation foundation

Animation primitives (6 new components):
- AnimatedNumber: count-up with easeOutExpo, de-DE locale formatting
- ShimmerSkeleton: diagonal gradient sweep replacing animate-pulse
- FadeIn: framer-motion viewport-triggered fade + slide
- StaggerList/StaggerItem: staggered children entrance
- Sparkline: pure SVG inline trend chart with draw-in animation
- ProgressRing: animated circular progress with CSS transitions

Sidebar & page transitions:
- Sliding nav indicator (framer-motion layoutId animation)
- Icon frame hover glow (brand-color shadow)
- Smooth section collapse/expand (AnimatePresence height animation)
- PageTransition wrapper (fade-up on route change)
- AnimatedModal component (scale + fade with custom bezier)
- Notification badge bounce on count increase

Dashboard animations:
- StatCards: AnimatedNumber count-up + staggered FadeIn + budget color tinting
- WidgetContainer: fade-slide-up on mount
- Chargeability: animated percentages + inline utilization bars
- ProjectTable/MyProjects: animated numbers + staggered row entrance

Shimmer skeletons & table animations:
- Replaced animate-pulse across 20+ loading states with shimmer gradient
- Staggered row entrance (fadeSlideIn) on Resources, Projects, Allocations tables
- hover-lift utility class for subtle card/row elevation on hover
- Content-shaped skeletons (avatars, text bars, badges)

Light mode surface depth:
- Mesh gradient page background (subtle accent-tinted corners)
- Enhanced card shadows (two-layer depth)
- Sidebar glassmorphism upgrade (bg-white/60, backdrop-blur-2xl, saturate-150)
- Toolbar sticky backdrop blur
- Enhanced focus ring with brand-color glow
