Pull request overview

This PR refactors the internationalization (i18n) approach for field configurations by consolidating multiple language-specific YAML files into a single multilingual configuration file. Instead of fetching different files based on the active language (e.g., fields-en-GB.yaml, fields-es-ES.yaml), the system now fetches a single fields.yaml file once and resolves localized values at runtime when the language changes.

Key Changes

• Introduced a resolveLocale helper function to extract language-specific values from locale maps
• Split the configuration loading into two phases: fetch once, re-parse on language change
• Updated YAML structure to store translatable fields as locale maps (e.g., label: { en-GB: "Name", es-ES: "Nombre" })
