/**
 * Journey: Budget Settings — Portfolio Spend Cap
 * SESSION: 159f8710-4ca5-4762-9d9f-b53c4d954ad1
 *
 * Verifies the Budget.tsx page (Settings/Budget):
 *  - Page renders with cap form and pause toggle
 *  - Pause toggle hides the cap input and changes the save-button label
 *  - Restoring from pause restores the last non-zero cap
 *  - Submitting a cap value succeeds without JS errors
 *  - Clearing the cap (blank) succeeds and shows the plan-default hint
 *  - Client-side $0-cap hint redirects user to the pause toggle
 *  - Unauthenticated access is redirected to /login
 *
 * Background-request noise (test-env artifacts):
 *   - /api/lead-score/pql-signal 401 — Sanctum statefulDomains mismatch on non-8000 ports
 *   - PATCH /profile 419 — timezone auto-detect CSRF timing on fresh session
 * These occur on ALL authenticated pages in this env — not Budget bugs.
