v0.40.0

Added

• Budget loans tracker (PR #117 by @rafaelfoster): a new Loans tab in the Budget module lets you create instalment-based loans, record individual payments, track remaining balance and due months, and filter budget transactions by loan. Paid-off loans are automatically marked as closed. Full CRUD with confirmation modals.
• Dashboard widget sizes: each dashboard widget now has a configurable size (columns × rows). Sizes are persisted in user preferences and survive page reloads.
• Extended date formats: Settings → General now offers four additional date format options — MM.DD.YYYY, YYYY.MM.DD, YYYY/MM/DD, and DD/MM/YYYY — alongside the existing formats.

Fixed

• dmy date format preserved: the existing DD.MM.YYYY behaviour of the dmy preference is unchanged for all current users; a new DD/MM/YYYY option (dmy_slash) is available for those who want slashes.
