Miscellaneous fixes (#22828)

* fix video playback stutter when GenAI dialog is open in detail stream

Inline `onOpen` callback in DetailStream.tsx:522 creates a new function identity every render. GenAISummaryChip.tsx:98's useEffect depends on [open, onOpen], so it re-fires on every parent re-render while the dialog is open. Each fire calls onSeek -> setCurrentTime -> seekToTimestamp, creating a continuous re-render + seek loop

* add /profiles to EXEMPT_PATHS for non-admin users

* skip debug_replay/status poll for non-admin users

* use subquery for timeline lookup to avoid SQLite variable limit
