feat(web): make customer survey non-blocking

[Drixled]

Summary

Moves the customer-source survey out of the onboarding path and into the authenticated app shell as a small, dismissible card. The existing persistence behavior stays the same, while the legacy survey URL now forwards users to its validated destination instead of blocking navigation.

What changed

• restyle the existing customer-source survey as a compact, dismissible card in the authenticated app shell
• remove the full-page survey redirect from onboarding navigation
• preserve the existing database field and submit/dismiss mutations
• forward the legacy survey URL to its validated destination
• update the existing account-verification assertions for the non-blocking flow
• remove the obsolete full-page survey E2E and redirect-helper tests

Visual review

The UI change is contained to the authenticated survey card. This PR does not include before/after screenshot assets.

Scope

• no database, API, telemetry, seed, or local-environment changes
• no new test files
• no changes to the existing survey persistence contract

Validation

• pnpm format
• pnpm --filter web test -- "src/tests/account-verification-redirect.test.ts"
• pnpm --filter web typecheck
• pnpm --filter web lint

WARNING: Survey card is not excluded from onboarding/welcome flows

<CustomerSourceSurvey /> is mounted unconditionally in the (app) layout, so it renders on every route under this layout, including /gastown/onboarding (apps/web/src/app/(app)/gastown/onboarding) and the org welcome flow (apps/web/src/app/(app)/organizations/[id]/welcome). The PR description states a goal of "stop the survey from intercepting onboarding navigation," but there is no path-based exclusion here (unlike the shouldShowCustomerSourcePrompt gating that existed earlier in this branch's history and was dropped). The card is non-blocking for routing, but it will still visually overlay the onboarding wizard and org welcome screens.

Executive Summary

The non-blocking survey card is mounted globally in the (app) layout with no exclusion for onboarding or org-welcome routes, which runs counter to the PR's stated goal of not interfering with onboarding.
