Add database cleanup feature to empty all sensor tables

Browse Source 
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
