feat: dynamic app catalog, Gitea app polish, registry sync

App catalog served from Gitea repos (app-catalog) with 35 apps.
Nodes fetch catalog dynamically — new apps appear without frontend
rebuild. Test app added and removed to verify pipeline.

Gitea manifest updated with internal_port/nginx_proxy for iframe.
Updated catalog.json, nginx configs, app session configs.
