Marco 179b59d73d Redesign invoice PDFs, add correction-invoice downloads, return reasons, and per-product tax/bundle support
Invoice + Stornorechnung/Gutschrift PDFs get a modern header-band layout,
a "bereits beglichen" badge for immediately-paid orders, labelled bank
details, and a per-tax-rate summary breakdown. Correction invoices can
now be re-downloaded from the account (regenerated deterministically,
not stored as files, same approach as the original invoice). Return
requests capture a reason. Products can define bundles (bundleItems) and
a per-product VAT rate override, both snapshotted onto order items.
