fix: Gitea Traefik routing and connection pool optimization

- Remove middleware reference from Gitea Traefik labels (caused routing issues)
- Optimize Gitea connection pool settings (MAX_IDLE_CONNS=30, authentication_timeout=180s)
- Add explicit service reference in Traefik labels
- Fix intermittent 504 timeouts by improving PostgreSQL connection handling

Fixes Gitea unreachability via git.michaelschiemer.de

+/**
+ * Event Bus Module
+ * 
+ * Provides centralized event system for cross-module communication.
+ * 
+ * Usage:
+ * - Add data-module="event-bus" to enable global event bus
+ * - Or import and use directly: import { EventBus } from './modules/event-bus/index.js'
+ * 
+ * Features:
+ * - Pub/sub pattern
+ * - Namespaced events
+ * - Event filtering
+ * - Event history
+ * - Integration with LiveComponents
+ * - Integration with SSE
