* fix(ui): block illegal VAT rates, honest opening-balance state, surface account-save errors - Supplier invoice form (#863 item 1): onSubmit now blocks any non-reverse-charge line whose VAT rate is outside the legal Swedish set {25, 12, 6, 0} with a destructive toast naming the line and the legal rates. Server-side schema tightening stays out of scope. - Opening balance import (#837): the summary derives isBalanced from the running totals (0.01 epsilon) and renders the AlertCircle destructive pattern with the differens amount when unbalanced; canExecute includes isBalanced so the commit button is disabled instead of funneling users into a server-side rejection. - EditAccountDialog (#838): a failed account save now shows a destructive toast with the server-provided message instead of being silently swallowed; the dialog stays open for retry. Co-Authored-By: Claude Fable 5 <noreply@anthropic.com> * fix(ui): compare opening-balance totals in whole ore, map account-save errors to Swedish Review findings on the first pass: the < 0.01 epsilon misclassified exact 1-ore imbalances as balanced (0.03 - 0.02 evaluates just under 0.01), and the save-failure toast surfaced raw English server text instead of routing through getErrorMessage like the sibling handlers in the same file.
