Subject: [PATCH] feat: implement language-based email template selection
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Update email worker to select templates based on BillingLocation.tenantEmailLanguage:
- Change default language from 'en' to 'hr' in emailTemplates.ts
- Pass language parameter (location.tenantEmailLanguage || 'hr') to all loadAndRender calls
- Applies to email validation, rent due, and utility bills notifications

Email templates are now automatically selected based on tenant's language preference,
defaulting to Croatian when not specified.
