Fix diagnosis print template dual-PDF flow and settings save bug

- Diagnosis.php: resolve doctor mapping via ABDM Report Doctor Mapping,
  compile pathology/diagnosis reports into separate Letter Head and
  Plain Paper PDFs, add compiled-pdf-links endpoint
- Routes.php: add diagnosis/compiled-pdf-links route
- pathology_detail.php: render/persist dual compiled PDF buttons
- Setting/Template.php: per-modality Letter Head / Plain Paper template
  mapping via hospital_setting keys
- Setting/Template/index.php: fix tile links using load_form (which only
  replaces #main) instead of load_form_div, which broke every internal
  AJAX reload (template type switch, modality switch, reset) on the
  diagnosis/discharge/document print template settings pages
- diagnosis_print_settings.php: fix corrupted watermark_alpha number
  input (missing step attribute) that silently blocked form submission
  for templates with non-integer-step legacy values
