- toggleCompanyHoliday now calls loadStats() so the entitlement sidebar
updates immediately when a vacation day is converted to a company holiday
- deleteYear now deletes vacay_user_years rows for the removed year,
preventing stale entitlement data from persisting and re-appearing
when the year is re-created
- deleteYear recalculates carry-over for year+1 when year N is deleted,
using the new actual previous year as the source
- removeYear store action now calls loadStats() so the sidebar reflects
the recalculated carry-over without requiring a page refresh
- Add prev-year button (+[<] 2026 [>]+) so users can add years going
backwards after deleting a past year; add vacay.addPrevYear i18n key
to all 13 supported languages
Closes#371
When deleting the currently selected year, selectedYear was never
cleared, leaving the deleted year shown as active in the UI. Now
resets to the latest remaining year, or the current calendar year
if all years have been removed.
Fixes#369
