Added

• Number and currency formatting now follows your selected Region, not just the display language (#521). Picking "Deutsch (Schweiz)" (or any region) under Settings > Personal > Appearance now formats amounts with that region's grouping and decimal separators, for example the Swiss 123'456.78 instead of 123.456,78, across Budget, Subscriptions, Split Expenses, Housekeeping, Rewards, Health and the Dashboard. This is independent of the interface language, so a German-language household can still display Swiss-formatted numbers. Previously formatting was tied to the two-letter language code and there was no way to reach the Swiss (or any region-specific) number format.

Changed

• The Region setting's hint now states that it also controls the number format and shows a Swiss example, so the feature above is discoverable at the point of decision (all 23 languages). The hint is now announced to screen readers together with the selector, and non-admin members see a short "only administrators can change region and format" note instead of an empty heading.
• Number formatters are now cached per region and options instead of being rebuilt for every displayed value, reducing redundant work on money-heavy screens.

Fixed

• Budget CSV export no longer risks splitting the amount into two columns. The amount was formatted with a comma decimal separator inside a comma-delimited file, which could break the column in spreadsheet imports; it now uses a dot decimal without thousands grouping, which is unambiguous and matches the region-aware on-screen format for dot-decimal locales (#521).
