fix(reconciliation): exclude ignored transactions from the bank total and bridge whitespace-drifted duplicate descriptions (#1705)

Bank reconciliation counted ignored transactions in bank_transaction_total
while excluding them from the unmatched count, so after the sanctioned
duplicate cleanup (ignore one twin) the differens showed the ignored sum
forever and is_reconciled was unreachable: observed live as a permanent
116 367 kr differens on a fully booked enskild firma (78 867 kr ignored
reconnect duplicates + 37 500 kr genuinely unbooked). The ignore toast
already promised 'försvinner från avstämningen'; now the engine keeps
that promise. Ignored rows are surfaced separately (count + sum) in the
status object, the UI card, and the v1 API, mirroring the IB pattern.

The duplicates themselves came from a PSD2 reconnect: the new connection
re-rendered identical transactions with drifted whitespace (CRLF vs
space, and a DROPPED space), so the prefix-containment content bridge
missed every twin. descriptionsBridge now strips all whitespace before
comparing: char-filtering preserves existing prefix relations, and the
compare stays confined to a (date, öre) bucket.

 [2026-08-18] Migration-reset eligibility treats every persisted Skatteverket VAT `submission_*` workflow row as authority interaction evidence, not only successful audit-log rows: historical direct locks stored the signing state without auditing it, and Accounted cannot observe whether a user completed BankID signing outside the app. Unsigned drafts must be removed through the product; locked or uncertain state fails closed and is escalated.
 [2026-08-18] Migration-reset eligibility also blocks AGI `pending_signature` and `agi_submission_*` state plus every ROT/RUT payout request: both flows hand work to Skatteverket for external upload or BankID signing before Accounted can observe the filing outcome, so a missing receipt or locally generated/cancelled status cannot prove that the data is disposable.
 [2026-08-19] Keep reversal allocation metadata limited to failures before any reversal header exists: later cleanup preserves a cancelled header with the allocated voucher number, so documenting it as an unused voucher gap would be false.
+[2026-08-19] Bank reconciliation: ignored transactions are excluded from bank_transaction_total/difference (surfaced as separate count+sum) rather than keeping the old "what the bank moved" semantics: the ignore flag's dominant real-world use is feed duplicates (which never moved money and never get a ledger leg), so including them made is_reconciled unreachable after a correct dupe cleanup (observed: permanent 78 867 kr differens on a fully booked EF account). descriptionsBridge now strips ALL whitespace before the prefix compare (collapse-only still misses a dropped space); safe because char-filtering preserves prefix relations and the compare stays inside a (date,ore) bucket.
 [2026-08-19] Inline rättelse bank guard anchors to the linked bank amount, per account, not to the pre-state and not to the 19xx group net: a non-zero change on a 19xx/cash-ledger account is allowed iff the post-state net on that account equals the signed sum of the linked transactions resolved to it (once per transaction, split links by allocated_amount; NULL cash_account_id resolves to the primary cash account, then 1930). Per account rather than group so a wrong-bank-account booking (1930 vs 1940) stays a storno job: a group check would let the net drift between accounts and break per-account bank reconciliation. When no anchor resolves the old strict refusal stands. Reskontra sides (15xx/24xx) stay strictly net-preserving because their anchor is the payment row, not a bank amount.
