Frontend CI failed on @typescript-eslint/no-explicit-any in three L1
post-review fix sites. Replace `(err as any).response...` with the
codebase's established structural cast
`(err as { response?: { data?: { detail?: string } } })`, matching
TicketPickerModal / FolderEditModal / ProceduralEditorPage. The
AccountSettingsPage 402 handler gets the fuller seat-limit detail shape.
tsc clean, eslint clean.

Final review flagged silent failure on intake error. Adds a toast with
the backend detail message (or fallback) on catch.

Replaces the T20 stub. L1 dashboard renders greeting, "Describe the
problem" intake card (autofocus textarea, optional customer fields,
primary "Start walk" CTA), open-tickets queue (Phase 1: display-only),
and a "Resume in progress" widget listing the L1's active sessions
ordered by last_step_at DESC. Empty-state card shows on accounts with
no queue + no active sessions (first-run nudge to upload KB or auth flows).
Adds /api/l1.ts (full L1 API client surface) and /types/l1.ts.

L1RouteGuard wraps the new routes and redirects users without
canUseL1Surface back to /. Page components are stubs in this task
(real UI in T21-T24): L1Dashboard, L1WalkPage, L1DraftsPage,
L1TicketsPage.
Routes: /l1, /l1/walk/:sessionId, /l1/drafts, /l1/tickets — all gated.
