refactor: Integrate Modules into Scope-Decision (Option C)

- RegulationsPanel: added enable/disable toggles per regulation
- ScopeDecisionTab: passes enabledModules + onToggleModule
- Scope page: auto-enables all applicable regulations when loaded
- Modules step: isOptional=true, moved to Zusatzmodule
- Requirements: now depends on compliance-scope, not modules
- Source-policy: now depends on use-case-assessment, not modules

Flow: Profile → Scope → Scope-Decision shows applicable regulations
with toggles → Requirements derived from enabled regulations
