Pull request overview

This PR introduces a new Gascan execution plugin to SEP, including both the legacy Jinja UI routes and the schema-driven React SPA integration via the /api/plugins/gascan/ gateway.

Changes:

• Add Gascan backend plugin (HTML routes + JSON plugin API) with schema, models, deps, templates, and mount configuration.
• Add a schema-driven React plugin package and wire it into the shell router/navigation.
• Extend task ownership enum (TaskOwner) to include GASCAN, and add tests covering Gascan deps and routes.
