A render error in one viewer or gate widget unmounted the whole React root
(white screen). Add a reusable ErrorBoundary (class component, no new dep) with
resetKeys + an on-brand fallback, and wire it at two surfaces:
- WidgetHost: isolates the gate widget (reset on descriptor id) so a malformed
gate payload no longer blanks the conversation
- SessionDocumentsPanel: wraps each document (reset on doc key/content) so one
crashing viewer degrades only its section; siblings and the panel survive
The observed crash: a schema-linking doc that parses but lacks `candidates`
makes SchemaLinkingViewer throw. Verified live via Playwright against the mock
backend. TDD throughout; tsc clean, 123/123 vitest (+8 new tests).

The interface is now fully English regardless of the chat language (session
titles stay in whatever language the user typed). Changed the right-rail
subtitle to 'Datamart Builder with Human In The Loop'. Translated all chrome:
new-question/settings dialogs, workflow phase strip (F1-F8), session rail,
steer input, widgets (select/multiselect/freetext/fallback/reserved controls)
and viewers (SQL, results, schema linking). Test matchers updated in lockstep.

- sessionStore.applyEvent: on ui_request set currentPhase normalized from the
descriptor's phase to its short id (e.g. "F4_schema_linking" -> "F4"), so
WorkflowBar actually highlights the active phase; falls back to the existing
phase when the descriptor has none. setPhase kept for resume/getSession.
- Add pushToast store action; WidgetHost wraps postResponse in try/catch,
pushes an error toast and keeps the widget pending on failure (clearPending
only on success) so the user can retry.
- Tests: store currentPhase normalization + no-phase passthrough + pushToast;
new WorkflowBar.test.tsx asserting the matching phase is highlighted.
