feat: Template-Spec v1 Phase C — IF-Renderer + HOSTING/FEATURES + 4 neue DE-Templates

- contextBridge.ts: HostingCtx + FeaturesCtx (35 Felder), ~50 neue Platzhalter-Aliases
- ruleEngine.ts: buildBoolContext() + applyConditionalBlocks() (IF/IF_NOT/IF_ANY)
- ruleEngine.test.ts: 67 Tests (+18 für Phase C), alle grün
- page.tsx: IF-Renderer in Pipeline, HOSTING+FEATURES Formular-Sections, erweiterter SDK-Prefill
- scripts/apply_templates_023.py: 4 neue DE-Templates (Cookie v2, DSE, AGB, Impressum)
