bokslut, INK2/SRU export and attachment markersv0.1.30

- bokslut.post: year-end bookings (manual entries, periodiseringsfond,
  skatt at a given rate, resultatdisposition) with a dry-run plan through
  the normal ledger path; the resultatrapport separates
  bokslutsdispositioner and skatt per K2.
- sru.export: INFO.SRU + BLANKETTER.SRU (INK2/INK2R/INK2S) from the
  official 2025P4 field tables and the BAS mapping, with manual INK2S
  adjustments, submitter defaults and unmapped-account detection; the TUI
  writes both files from Rapporter -> Inkomstdeklaration.
- voucher.list carries attachment_count and the voucher list marks
  vouchers with underlag with an x column.
- date_prompt restores the cursor state so it stops blinking at the bottom
  after the report date prompts.
