Add login page (LIM-292)

[muvaf]

Summary

Closes LIM-292.

Adds a polished SwiftUI login screen as the app's entry point.

What's included

• New LoginView.swift with:
  • Email field with validation (regex check)
  • Password field with show/hide toggle and 6-char minimum
  • "Remember me" checkbox and "Forgot password?" link
  • Gradient "Sign In" button (disabled until form is valid) with loading spinner
  • "Continue with Apple / Google" placeholder buttons
  • "Sign Up" footer link
  • Inline error messaging
  • Gradient background and rounded card layout
• ContentView.swift now hosts LoginView inside a NavigationStack
• After a successful sign-in, the user is navigated to a simple HomeView that confirms they are signed in
• All key controls have accessibility identifiers for UI testing (emailField, passwordField, signInButton, etc.)

Testing

Built and ran the app on a remote iOS simulator via lim CLI; verified end-to-end happy-path login flow and validation behavior. Demo video and screenshots attached below.
