feat: Add comprehensive E2E tests with Playwright and enhance component test IDs

Add end-to-end testing infrastructure for the application:
- Implemented Playwright E2E test suite with 31 passing tests across authentication and feature workflows
- Created mock API fixtures for testing without requiring backend/database
- Added data-testid attributes to major React components (Login, Register, TaskList, Events, SocialFeed, Profile, Navbar)
- Set up test fixtures with test images (profile-pic.jpg, test-image.jpg)
- Configured playwright.config.js for multi-browser testing (Chromium, Firefox, Safari)

Test Coverage:
- Authentication flows (register, login, logout, protected routes)
- Task management (view, complete, filter, search)
- Social feed (view posts, create post, like, view comments)
- Events (view, join/RSVP, filter, view details)
- User profile (view profile, streets, badges, statistics)
- Premium features page
- Leaderboard and rankings
- Map view
