Update README with local screenshots and comprehensive page documentation

[Copilot]

Plan: Add Screenshots to README and Explain Pages

• Review existing screenshots in the screenshots/ directory
• Update README.md Screenshots section to use local screenshot files
• Add detailed explanations for each page:
  • Soundscape Creator - explain text prompts, voice input, 4-channel mixer
  • Preset Manager - explain browsing, searching, favorites
  • Playlist Manager - explain playlist creation and management
  • Settings - explain configuration options
• Ensure screenshots match the pages being described
• Verify markdown formatting and image links work correctly
• Add ALL screenshots from the screenshots folder (11 total)
• Fix failing test: updatePlaylist updates playlist fields

• Added 06-soundscape-updated-design.png showing the updated Soundscape Creator design

Test Fix

Fixed the "updatePlaylist updates playlist fields" test failure by adding a 10ms delay between creating and updating the playlist. This ensures that updatedAt and createdAt timestamps are different, even in fast CI environments where operations can complete in the same millisecond.

add the new screenshots to the readme and explain the pages
