Initial commit: one_os_compositor Odoo 20 addon — core OWL library + backend models + JWT auth

Includes:
- compositor.app, compositor.session, compositor.session.app, compositor.audit.log models
- /web/compositor/{token,apps,launch,audit} HTTP controllers with JWT (HS256)
- CompositorService OWL service (reusable via useService('compositor'))
- CompositorCanvas OWL component (reusable canvas wrapper)
- Security: compositor_group_user, compositor_group_manager groups + ir.access.csv rules
- 5 demo apps pre-loaded (gnome-calculator, xterm, gtk4-demo, glxgears, featherpad)
- Audit log capturing JWT issuance + app launch events
- Stub mode: launching apps returns a stub SurfaceHandle when proxy isn't connected
- Tested against Odoo 20 + PostgreSQL 17
