add default Homepage annotations to ingress_factory for auto-discovery

- ingress_factory now injects gethomepage.dev/* annotations on all ingresses
  (name, group, href, icon) with namespace-to-group mapping
- Stacks with explicit annotations override defaults via merge order
- New homepage_enabled var allows opt-out for internal-only ingresses
- Homepage search widget switched to in-page quicklaunch (Ctrl+K / tap)
- Added hideErrors and quicklaunch settings for clean service directory
- Result: 116/134 ingresses now discoverable (up from ~30)
