feat(client): LT Wahl admin, Teamer admin, Verantwortlichen self-registration

New screens (client/app/lib/screens/): - wahl_admin_screen.dart — per KC: list/create Wahlen; per Wahl: add workshops, run the assignment (POST /wahl/:id/zuteilung/run), view the result table. - teamer_admin_screen.dart — per Gemeinde: list/create local Teamer accounts, create group-link or per-email invites (shows the token). - verantwortliche_register_screen.dart — enter a KC invite code (GET /onboarding/kc/:code), pick a Gemeinde, submit (POST /onboarding/verantwortliche); shown on the home screen to a logged-in Authentik user who has no membership yet. - ui.dart — shared toast / ErrorText / SectionHeader / promptText. KcDetailScreen now links to Wahl admin and each Gemeinde row opens Teamer admin. Backend: widen the wahl + files LT routes to AuthGuard(['authentik','team']) for consistency with the other LT controllers. Rebrand web/index.html + manifest from "kc_app" to "KC-App". Verified against local Postgres with an isLeitungsteam team token: create KC/Gemeinde/Wahl/Workshop, run Zuteilung, create Teamer + invite, resolve an invite code. flutter analyze/test/build web green; backend npm test 56.
