Add a `toError` utility function to `@backstage/errors` that converts unknown values to `ErrorLike` objects. If the value is already error-like it is returned as-is. Strings are used directly as the error message, and other values are stringified with a fallback to JSON.stringify to avoid unhelpful `[object Object]` messages. Non-error causes passed to `CustomErrorBase` are now converted and stored using `toError` rather than discarded. Existing `assertError` call sites across the codebase are migrated to `toError`.
