fix(pitch-deck): HowItWorks line behind icons, remove France refs, SOM label

- Connection line: starts/ends between icons, opaque icon background
- Remove all "oder Frankreich/or France/oder FR/or FR" references
- Market subtitle: remove "Der Maschinenbau"
- SOM label: add "(nur Maschinen- und Anlagenbauer als Kernmarkt)"
