Fix lint errors: proper typing, unused vars, next/image, Playwright config

- dynamodb.ts: let → const for dynamoFailed (never reassigned)
- UserMenu.tsx: <img> → next/image <Image>, add Google domain to next.config
- color-sound: remove unused useRef import
- chat/speech: replace any types with SpeechRec interface, remove unused audioRef
- Remove stale eslint-disable directives
- Playwright: use next start (production) instead of next dev, add bypassCSP
