feat(install): route any manifest-known app through the orchestrator

package.install routed to the manifest-driven orchestrator only for a
hardcoded per-app allowlist; every other app fell through to the legacy
flow, which ignores manifests entirely and creates a bare container with
no ports or volumes (strfry crash-looped this way on .228, 2026-07-09).

New ContainerOrchestrator::knows_app(app_id) (default false; prod checks
its loaded-manifest map, disk + signed-catalog overlay). The install gate
is now allowlist OR knows_app — no per-app Rust for manifest-driven apps,
matching the packaging invariant. Apps without a manifest keep the legacy
flow including the container-exists adopt block; the unknown-app_id →
legacy fallback inside the orchestrator branch is unchanged.

Tests: knows_app_reflects_loaded_manifests + install suite 37/37.
