fix bad merge: remove duplicate slide names + move CSS imports before tailwind

Merge conflict resolution incorrectly added Anhang: Annahmen and
Anhang: Go-to-Market twice. Remove the duplicates, keep only the
renamed Anhang: Systemarchitektur entry in the correct position.
Also move @import rules above @tailwind directives (Turbopack CSS spec).
