fix: org-modern hook+after!, fragtog named fn, super-agenda zjednodusena config

- org-modern: pouzit :hook s pojmenovanou funkci my/org-modern-maybe
  + after! blok ktery aplikuje org-modern i na uz otevrene buffery (inbox.org)
- org-fragtog: same pattern, pojmenovana fn my/org-fragtog-maybe
- org-super-agenda: odebrana skupina Brzy (before +3d nespolehliva v quoted list),
  org-super-agenda-mode presunuto do after! bloku (jistejsi load-order)
