Replace 21 raw page.locator/getByTestId/getByText calls in the spec body
with named DSL operations in helpers/settings.ts. Each test body now reads
as prose: open settings, navigate to section, expect content.
New helpers: openCompactSettings, expectCompactSettingsList,
expectSettingsSidebarVisible/Hidden/Sections, goBackInSettings,
expectSettingsBackButton, clickSettingsBackToWorkspace,
verifyLegacyHostSettingsRedirect, openCompactSettingsHost,
expectHostSettingsUrl, expectAddHostMethodOptions, fillDirectHostUri,
expectDirectHostFormValues, expectDirectHostSslEnabled,
expectDirectHostUriValue/Hidden, expectDiagnosticsContent,
expectAboutContent, expectGeneralContent.
Export requireServerId from sidebar.ts so helpers encapsulate serverId
logic — spec has no direct env reads.
Also fix pre-existing typecheck error in use-keyboard-shortcuts.ts:
cast action.route to the expo-router Href type at call sites.
Adds a `withWorkspace` Playwright fixture plus composable helpers
(permissions, sidebar, composer, agent-stream, settings) so specs read
as user-level intent. Migrates workspace-lifecycle and settings-host-page
to the new DSL as proof.
