feat: add doctor view page with surgery history

[kasvith]

Summary

• Add new /doctors/:id view page that displays doctor information and their surgery history
• Add listSurgeriesByDoctorId backend API to query surgeries where a doctor was involved (as surgeon or assistant)
• Support filtering surgeries by role (All/Surgeon/Assistant) using tabs
• Update navigation to use view page instead of edit page (doctor list, command palette)
• Fix query cache invalidation after editing a doctor
