Add Workspace Created and Payment Received ClickHouse events (#20277)

## Summary
- Adds two new workspace audit events for the AARRR funnel tracked in
ClickHouse
- **Workspace Created**: emitted in `signUpOnNewWorkspace` after the
transaction commits, capturing every new workspace creation
- **Payment Received**: emitted in `processInvoicePaid` on every Stripe
`invoice.paid` webhook, with `stripeInvoiceId`, `amountPaid`, and
`billingReason` properties. First payment per workspace can be derived
at query time via `min(timestamp)` grouped by `workspaceId`

## Test plan
- [x] Verify `Workspace Created` event appears in ClickHouse after
signing up on a new workspace
- [x] Verify `Payment Received` event appears in ClickHouse after a
Stripe `invoice.paid` webhook fires
- [x] Confirm no event is emitted if the billing customer cannot be
resolved from `stripeCustomerId`
- [x] Run existing `SignInUpService` unit tests pass with the new
`AuditService` mock
