hyprlock: pin label font + flesh out ARCHITECTURE description

Final-review caveats:
- ARCHITECTURE.md hyprlock section was a generic one-liner inherited
  from gtklock; now mentions fprintd integration + GPU + blur.
- hyprlock label blocks didn't set font_family; clock/date now
  pinned to JetBrains Mono Nerd Font (same as rest of desktop).
