Add interactive demo components and feature sections to homepage

- Introduced `DemoSection`, showcasing live feature demos with interactive cards and test credentials for admin and auth flows.
- Added `FeatureGrid` with dynamic animations, highlighting major application features like RBAC, documentation, and deployment readiness.
- Built reusable `FeatureCard` for feature details, including icons, descriptions, and CTAs.
- Implemented `TechStackSection` to display modern tools and technologies used in the stack with tooltips.
- Updated dependencies: added `framer-motion`, `lucide-react`, and `react-syntax-highlighter`.
