Fix frontend error handling and code quality (GRO-642)

HIGH Priority:
1. SetupWizard.jsx -> SetupWizard.tsx: renamed to .tsx with proper TypeScript types
2. deleteAppt missing error handling: added try/catch, response.ok check, alert on failure
3. GlobalSearch missing error state: added error state with user-visible error message

MEDIUM Priority:
4. CustomerPortal unsafe type cast: fixed 'as any' to proper PortalAppointment type
5. Logo upload XSS risk: sanitized MIME types to png/jpeg/gif/webp only, removed SVG
6. Reports error handling: added ok checks before json() parsing to guard against invalid JSON on error responses

LOW Priority:
8. Modal accessibility: added role='dialog', aria-modal='true', focus trap, Escape key handler, restore focus on close
9. PetPhotoUpload file size: added 50MB max file size check before resize
10. Types package: added photoKey and photoUploadedAt to Pet interface
