* feat: implement fiscal period date fields component and validation logic
* feat: update fiscal period validation and naming logic
* feat: implement RPC for computing prior opening balances
- Added `compute_prior_opening_balances` RPC to aggregate opening balances for balance-sheet accounts when no opening balance entry is set.
- Updated tests across various reports to utilize the new RPC for fetching prior balances.
- Refactored `getOpeningBalances` to call the RPC when necessary, improving performance and reliability.
- Introduced a script to repair fiscal period chains for companies with broken periods, ensuring proper linking and continuity.
- Enhanced error handling and validation in the repair script to ensure data integrity during the process.
* feat: implement duplicate opening-balance repair for multi-year SIE imports
* feat: enhance SIE entry listing and deduplication logic for opening balances
* fix: refine companyHasPriorActivity logic to exclude storno entries and improve balance counting
* 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.
