/**
 * Validate every collection in a configuration.
 *
 * Enforced rules:
 *  - No field (at any nesting depth) may be named `path`. The `path`
 *    column on `documentVersions` is system-managed; collections opt
 *    into derived paths via `useAsPath`.
 *  - When `useAsPath` is set, the referenced field must exist at the
 *    top level of the collection and be of a type the slugifier can
 *    sensibly consume (text-like, date-like, or a numeric identity
 *    field — `integer` / `counter`).
 *  - No field may be named `availableLocales`; collections opt into the
 *    editorial available-locales control via `advertiseLocales: true`.
 *  - When `advertiseLocales` is `true`, the collection must have at least
 *    one `localized` field — advertising content locales is meaningless
 *    otherwise.
 *  - A collection may not set both `tree: true` and `orderable: true`. A
 *    document-tree owns ordering per-parent on the tree edge, so
 *    `byline_documents.order_key` is inert for it.
 *  - Each `listSearch` entry must name an existing top-level field whose
 *    type is persisted to the text store (the admin list-view search box
 *    is an `ILIKE` over `store_text`), and the field may not be virtual.
 *  - `virtual` fields must satisfy the constraints in
 *    {@link validateVirtualFields} (optional-or-default, no counters, no
 *    upload fields, not referenced by useAsTitle / useAsPath / search).
 *
 * Throws a plain `Error` (not a `BylineError`) because configuration
 * validation runs at startup, before the logger and error registry are
 * necessarily wired up.
