* feat(import): support Wise balance statements
* fix(import): fail closed on ambiguous Wise rows
* fix(import): guard Wise statement netted-fee assumption with running-balance continuity check
Swedish accounting review asked whether balance-statement Total fees is
netted into Amount. It is: Running Balance moves by exactly the signed
Amount per row, so a separate fee row would double-count the cost. Codify
the assumption with a pairwise continuity warning (order-agnostic, chain
resets across skipped rows) and document the decision.

* fix(api): cap bank-import validation payload and harden issue assertion
CodeRabbit review: bound the VALIDATION_ERROR issues array to 20 entries
with issue_count carrying the full total, so a large malformed file cannot
balloon the response or log sink. Gate stays format-agnostic on purpose:
error severity means do-not-ingest for every parser, and no non-Wise parser
emits per-row errors alongside parsed transactions today.
