Added a "Danger Zone" section on the database page that allows users to empty all sensor data tables while preserving configuration and timestamp tables. The feature includes:
- New Python script (sqlite/empty_sensor_tables.py) to safely empty sensor tables
- Backend endpoint in launcher.php (empty_sensor_tables)
- Frontend UI with red warning card and confirmation dialog
- Detailed feedback showing deleted record counts per table
- i18n support for French and English
Tables emptied: data_NPM, data_NPM_5channels, data_BME280, data_envea, data_WIND, data_MPPT, data_NOISE, modem_status
Tables preserved: timestamp_table, config_table, envea_sondes_table, config_scripts_table

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

Extended the internationalization system to support sidebar navigation menu with French/English translations. Fixed language selector dropdown styling to improve text visibility with proper contrast (gray background instead of transparent).
