Add roles CRUD backed by system_roles tables, session list/revoke APIs,
capabilities fallback for memory mode, and route all admin checks through
AuthorizationService instead of hardcoded role-admin checks.

Unify auth middleware and remove X-User-ID trust, add project_members
authorization, sandbox workspaces via resolver, and admin-only reconcile
by run_id. Introduce goose migrations with startup schema gate, fail closed
when DB unavailable outside explicit ALLOW_IN_MEMORY, bundle web/dist in
app Dockerfile, and remove frontend pseudo-login fallback.
