Enable tax collection on a bill.com connection

Provision the Bill.com invoice webhook subscription (if needed) and enable tax calculation (L2) on a Bill.com connection. Unlike the generic enable-tax-collection action, this is required before a Bill.com connection can enable tax collection at all. A no-op that returns the connection's settings unchanged if it is already enabled and configured. Returns 400 if the connection is not ready for tax calculation. Returns 404 if the connection does not exist, is not a Bill.com connection, or belongs to an organization your credential cannot access. A multi-org credential must send an `Organization-Id`, `Connection-Id` or `Entity-Id` selector, or gets a 400. Returns 503 if provisioning the webhook subscription fails; retrying may succeed.
