* feat: make invoice_number nullable and assign on send
- Updated the invoices table to allow invoice_number to be nullable.
- Modified the logic to assign invoice numbers only when the invoice status transitions to 'sent'.
- Refactored related code to handle nullable invoice numbers, including UI components and API routes.
- Added tests to ensure correct behavior when handling invoices with null invoice numbers.
- Introduced a utility function to display invoice numbers, defaulting to '(Utkast)' for drafts.
* fix: update fiscal period handling to return names of open periods in error messages
* fix: enhance period creation logic to account for company-wide bookkeeping lock-through
* fix: remove unnecessary customer_type field from customer insertion query
* fix: scope invoice number count query to specific companies to avoid test interference
* feat: Implement atomic invoice number generation and ensure compliance with invoice numbering rules
- Introduced `ensureInvoiceNumber` function to assign invoice numbers atomically, handling concurrency and ensuring compliance with document types.
- Updated invoice-related components to utilize the new `invoiceNumberDisplay` utility for consistent invoice number formatting.
- Added checks to ensure that invoices in non-draft statuses have valid invoice numbers, preventing violations of legal requirements.
- Created tests for the new invoice number generation logic, ensuring correct behavior under various scenarios, including concurrent requests.
- Added a draft banner to PDF templates for invoices without assigned numbers, clarifying their status to users.
- Updated database migrations to support the new atomic invoice number generation logic and enforce constraints on invoice statuses.
* feat: add fiscal period backward chaining and entry date validation
Support creating fiscal periods before the earliest existing period
(backward chaining) for backfill scenarios, alongside the existing
forward chaining. The engine now validates that entry dates fall within
the selected fiscal period, with a Swedish error message. The journal
entry form auto-selects the matching period and shows a warning with
a CreatePeriodDialog when no period covers the entry date.
* feat: support multi-bank-account for imports and reconciliation
Plumb a configurable settlement account through the entire bank import
pipeline — mapping engine, transaction entries, ingest, and
reconciliation — so secondary bank accounts (e.g. 1931, 1932) work
correctly instead of hardcoding 1930. Adds a get_unlinked_bank_lines
RPC that generalizes the existing get_unlinked_1930_lines with a
fallback for backwards compatibility. The bank file import UI now shows
a bank account selector when multiple 19xx accounts exist. Also adds
default_vat_code/sru_code to account creation and fixes uploadDocument
argument order in enable-banking sync.
