chore: Updated with-auth example

[thomasbuilds]

Summary

This PR enhances the with-auth example by introducing context-based session management for simpler integration with Vinxi sessions. It also adds start-oauth package for seamless OAuth flows, expanding beyond the existing (and non-production-ready btw) email/password flow.

To improve the user experience, TailwindCSS has been added alongside UI updates and a missing About page has been added too. The example still leverages unstorage for database-backed user management and keeps most of the existing logic.

Key Improvements

• Global Session Context – Centralized session access for cleaner and more maintainable code.
• OAuth Integration – Added start-oauth with sign in with discord
• UI/UX Enhancements – TailwindCSS styling and refined components.
• Example Expansion – Added the missing About page and improved structure.

Motivation

These changes make the example more realistic by showcasing context-driven session handling, OAuth integration, and improved design for better clarity and usability.
