Feat/voucher docs (#664)

* feat: implement inbox document picker and linking functionality

* feat: implement self-billing invoice functionality

- Added support for registering self-billed invoices received from customers.
- Updated the invoice schema to include fields for self-billing metadata such as `is_self_billed`, `external_invoice_number`, `self_billing_agreement_ref`, and `received_date`.
- Created API route for handling self-billed invoice submissions, including validation and error handling.
- Implemented database migrations to add necessary columns and constraints for self-billing invoices.
- Developed tests to ensure correct behavior of self-billing invoice creation and validation rules.
- Updated Swedish localization files to include new terms related to self-billing.

* feat: enforce SIE import requirement for non-Fortnox providers in migration process

* feat: streamline invoice processing and enhance error logging across APIs

+// documents that have not yet been consumed (no supplier invoice, no journal
+// entry, not matched to a transaction, document not already linked) so the user
+// can attach one as underlag to the current verifikat. Picking one links the
+// document to the journal entry AND stamps the inbox item so it drops out of the
+// active inbox — see app/api/documents/[id]/link/route.ts.
+//
+// Each row carries a preview button (eye) that opens a quick dialog rendering
+// the document inline, so the user can confirm the right file before attaching.
+// Attaching is the row's primary click (fast path) and is also offered from
+// inside the preview dialog (preview → confirm).
