Inline item editing on details pages; fix Stripe receipt_email

Allow description, quantity, and price to be edited inline on Quote,
Job, and Invoice details pages without re-opening the wizard. Coating
and prep service rows remain read-only by design. Invoice editing is
gated to Draft/Sent/Overdue statuses; totals update live in the DOM.

Remove receipt_email from Stripe PaymentIntent creation so customers
can use any email they choose at checkout — Stripe validates format
and sends the receipt to whatever the customer enters in the Payment
Element, eliminating the risk of a stored email mismatch blocking a
payment from processing.
