fix(mcp): over-long reason gets VALIDATION_ERROR and a specific Swedish message (#1811)

* fix(mcp): over-long reason gets VALIDATION_ERROR and a specific Swedish message

gnubok_reverse_journal_entry / gnubok_undo_sie_import cap `reason` at 500
characters, but exceeding it produced code UNKNOWN_ERROR with message_sv
"Något gick fel. Försök igen." while the cause sat only in message_en.
getStructuredError now infers VALIDATION_ERROR from the message and
getErrorMessage maps it to "Motiveringen får vara högst 500 tecken.".

* fix(errors): pin the reason-length pattern to 500 and assert the envelope on undo_sie_import

Review findings: the Swedish message hard-codes 500, so the pattern must
match that limit only; the undo_sie_import 501-char test now asserts code
and both localized messages like the reverse test does.
