Replaced hardcoded German text in the envelope sharing UI and JavaScript alerts with localized resource strings for German, English, and French. Added new translations for labels, prompts, and error/success messages. Improved internationalization and user experience by making the sharing feature fully language-aware.
Added new resource strings for document signing success and confirmation messages in de-DE, en-US, and fr-FR. Updated EnvelopeSigned.cshtml to use these localized strings instead of hardcoded text.
Added new resource strings (prefix, link, suffix) for authenticator app setup instructions in German, English, and French resource files. Updated EnvelopeLocked.cshtml to assemble the instruction dynamically using these localized parts, ensuring correct grammar and flexibility across supported languages.
Added "DocumentSharingPeriodExpired" and "Expired" keys to de-DE, en-US, and fr-FR resource files. Updated EnvelopeExpired.cshtml to use localized strings for the title, heading, and message, enabling full internationalization of the expired envelope page.
Refactored Culture model to use required and non-nullable properties.
Removed nullable checks for Info in ShowEnvelope.cshtml.
Changed DI from Cultures to MultiCulture in _ViewImports.cshtml.
A "Refresh" button with a counterclockwise arrow icon is now shown in the envelope UI, but only when the envelope is not in read-only mode. The button uses standard styling classes for consistency.
