/**
 * Error-path coverage for the Add Repo and Add Plan dialogs: a wrong-password
 * rejection against a real repo, required-field validation, and the
 * paths-required rule for plans. In all three cases the primary assertion is
 * persistent state (the dialog stays open, nothing new appears in the
 * sidebar); the validation/error text is also asserted per the task brief,
 * even though it renders in a toast (see "Toast placement" note below).
 *
 * Toast placement: all of these errors surface via
 * webui/src/components/common/Alerts.tsx (`alerts.error` -> Chakra
 * `toaster`), which renders in its own top-level Portal
 * (webui/src/components/ui/toaster.tsx), not inside the dialog's DOM subtree.
 * So error text is asserted at the page level (`page.getByText(...)`), not
 * scoped to `dialog`. This is called out because the task brief allows
 * "error/validation text within the dialog" for these tests, but the current
 * implementation never renders these particular errors inline in the form —
 * they are only ever shown as toasts. Flagged as a gap below.
