Revert generalPartners, fix shareCapital: neither is a Pflichtangabe

Corrected after user feedback: Stammkapital/Grundkapital is only required on business correspondence if voluntarily disclosed in the first place (§35a Abs. 1 S. 2 GmbHG) — not an unconditional Pflichtangabe. shareCapital's Impressum rendering stays (shown only if an admin voluntarily filled it in), but it's dropped from the email/invoice footer.

generalPartners is removed entirely — the legal basis was genuinely unclear on research (§125a HGB's Geschäftsbriefe-naming duty only applies to the narrow case where no partner is a natural person; whether §5 DDG's Impressum-specific "vertretungsberechtigte Person" requirement independently mandates it for the general OHG/KG case wasn't resolved with confidence) — reverted rather than shipped on an uncertain legal basis.

Also fixes stale "§5 TMG" citations to "§5 DDG" (TMG was replaced 14 May 2024).
