Pull request overview

Adds a reconfiguration flow to the Indevolt integration so users can change the configured host address after initial setup, and marks the integration’s quality scale reconfiguration requirement as complete.

Changes:

• Implement async_step_reconfigure in the Indevolt config flow to validate the device at the new host and update/reload the config entry.
• Add UI strings for the reconfigure step and new abort reasons (successful reconfigure, different device).
• Extend config flow tests to cover reconfigure success, error recovery, and unique-id mismatch/different-device scenarios.
