- Fix total print hours calculation in set_total_hours to include all

    prints (not just completed), matching get_printer_total_hours behavior
  - Add option to keep or delete archives when deleting a printer
  - Custom maintenance types no longer auto-assign to all printers
  - Add UI to manually assign/remove custom maintenance types per printer
  - Add backend endpoints for assigning types to printers and removing items
  - Exclude static/assets from large file pre-commit check
  - Fix A1/P1 camera streaming with extended timeouts and lower FPS cap
