add option to create location in all subsequent months

- Added toggle in LocationEditForm for adding locations to future months (disabled by default)
- Modified updateOrAddLocation action to support batch creation across subsequent months
- Only creates locations in months where no location with same name exists
- Added translations for toggle text in Croatian and English
- Fixed unused variable warning in deleteLocationById
- Improved auth.ts development comments for clarity
