Update: Add EUR currency support for Slovak companies

Browse Source 
- Modified get_cz_qr_code_base64() to support both CZK and EUR
- Updated cz_to_iban() to better handle international IBANs (SK, etc.)
- SPAYD QR now uses actual invoice currency in CC: field
- Updated manifest description to reflect EUR support
- Updated README with setup instructions for Slovak companies

This allows Slovak companies with EUR accounts to generate SPAYD QR codes
for Czech customers, enabling cross-border EUR payments via mobile banking.
