docs(wiki): update handbook to v0.7.3 app state
Rebuild the end-user wiki to match the current application, integrated on
top of the latest remote wiki state:
- New pages: Discord-Anmeldung (login gate, admin approval, linking an
existing account), Organisation (OL/Bereich/Staffel/SK hierarchy,
replaces the old Spezialkommandos page), Kartellbank, Benachrichtigungen,
Desktop-Extractor.
- Rewrite Organigramm for the full OL/Bereich hierarchy and keep the
dedicated Blueprint-Verfuegbarkeit page (now the canonical home; the
Handel page points to it).
- Update every feature page (missions, operations, orders, refinery incl.
screenshot import, inventory, trade, hangar, personal inventory,
promotion, administration, FAQ) and the roles & permissions page
(bank roles, leadership cascade, Discord pending state).
- Replace the removed top-right context chip with the app title + sidebar
"Aktiver Bereich" switcher; fix krt-iri -> krt-profit URLs throughout.
