Add database cleanup feature to empty all sensor tables
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 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Sonnet 4.5 <noreply@anthropic.com>
