Add i18n translations for page content (Home, Database, Logs)

Extended internationalization support by adding translation keys and data-i18n attributes to page content. Previously only the sidebar was translated - now the main content of Home, Database, and Logs pages will switch between French and English when the user changes the language selector.

Translation keys added:
- Home page: title, welcome message, PM measures, Linux stats, disk/memory usage
- Database page: all UI labels, buttons, and dropdown options
- Logs page: title, description, log types, and action buttons
