Implement Phase 4 E2E tests: New User Chat Session

[ananthpai1998]

Add comprehensive E2E test suite for complete chat session user journeys:

• Test 1: Complete first-time user flow (navigation, registration, login)
• Test 2: API key entry and validation in localStorage
• Test 3: Model selection from dropdown
• Test 4: Sending first message
• Test 5: Receiving AI response
• Test 6: Multi-turn conversation with message persistence
• Test 7: Chat persistence after page refresh

The test suite includes helper functions for common operations:

• loginUser: Handles user authentication flow
• setApiKey/getApiKey: Manages API key in localStorage
• sendMessage: Sends chat messages and waits for display
• waitForAIResponse: Waits for streaming completion
• selectModel: Handles model dropdown selection

All 7 tests are properly structured using Playwright best practices with appropriate wait conditions, selectors, and assertions.

Updated docs/testing.md to mark all New User Chat Session E2E tests as completed [x].

Tests verified with: npx playwright test --list
Result: 7 tests successfully recognized in 1 file
