Fix a11y + comment style on work log payroll page

- Active breadcrumb item now has aria-current="page" so screen
  readers correctly announce the current page (Bootstrap 5 convention).
- Template section comments changed from {# --- #} to {# === #} to
  match the CLAUDE.md Python convention used elsewhere in the project.

No logic or rendering changes.
