attempt to resolve timeout issues

[jthrilly]

This pull request refactors and enhances end-to-end tests for the Participants page and the Complete E2E Test Protocol interview. Key improvements include better synchronization using Playwright's waiting mechanisms, improved test reliability, and enhanced readability through comments and structured actions.

Enhancements to Participants page tests:

• Improved page synchronization by replacing waitForTimeout with Playwright's waitForLoadState and auto-waiting assertions to ensure elements are fully loaded before interacting.
• Added explicit waits for modals, dropdowns, and other UI elements to appear or update before proceeding with actions, improving test stability. [1] [2]

Improvements to Complete E2E Test Protocol interview tests:

• Added explicit waits for UI elements (e.g., forms, prompts, and drag-and-drop targets) to ensure they are ready before interactions, reducing flakiness. [1] [2]
• Enhanced drag-and-drop interactions by waiting for target areas and verifying node placement after each action. [1] [2]
• Introduced Redux state validation (e.g., waitForNodeCount and waitForEdgeCount) to confirm application state updates after interactions. [1] [2]
• Replaced hard-coded delays with Playwright's waiting mechanisms for transitions between prompts and edge creation, improving test efficiency and reliability. [1] [2]

These changes significantly improve the reliability, maintainability, and clarity of the test suite.
