🧹 Move inline styles to CSS in TranscriptViewer and Fix Build

[alfieprojectsdev]

• 🎯 What: Moved inline styles from TranscriptViewer.tsx to main.css and replaced them with CSS classes.
• 💡 Why: Refactoring inline styles improves maintainability and readability of the component.
• ✅ Verification:
  • Visually verified the TranscriptViewer styling using a temporary test page and Playwright screenshot.
  • Fixed broken imports and incorrect method usage in SurveyWizard.tsx to enable successful build.
  • Added missing dexie dependency required by db.ts.
  • Ran existing tests (npx vitest run) and verified they pass.
  • Verified the project builds successfully (npm run build).
• ✨ Result: The TranscriptViewer component is now cleaner and uses external CSS. The project build is also fixed.
