"""Unit: manifest parsing for `bottle.egress.routes[]` (PRD 0017).

The route shape is new: `host` (required), optional `path_allowlist`,
optional nested `auth: { scheme, token_ref }`. Validation rules per
the PRD: empty `auth: {}` is an error, partial `auth` is an error,
auth omission means unauthenticated."""
