* 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.".
