Task 5: Billing::purchase() now checks SecretVault for a stripe.secret before
touching anything else — no customer, no plan lookup, no Order row — and the
customer reads a plain sentence instead of a 500 page. HttpStripeClient's own
secret() throws the same StripeNotConfigured exception rather than sending a
request with an empty bearer token and letting Stripe's 401 stand in for the
real cause.
isConfigured() was fixed alongside it: it used to call secret() too, which
would have turned every "is Stripe set up?" check (the checkout controller,
the catalogue sync commands) into an uncaught exception the moment a key went
missing — the opposite of what this task is for. It now reads the vault
directly.
The new guard is unconditional, including for the cart-only purchase types
(storage, addon, plan changes) that never call Stripe themselves — a cart
order nobody can ever pay for is pointless to create. That broke every
existing Billing/Cart/Downgrade test that calls purchase() without a stored
key; each affected fixture now deposits one via the new withStripeSecret()
Pest helper. A few of those tests (CustomDomainAccessTest, DowngradeTest) were
passing already but for the wrong reason — the new guard, not the check they
were named for — since both only assert an order was NOT created; they get
the same fixture fix so they still prove what they claim.
