fix: improve error handling in config flow for unexpected exceptions

[stuartp44]

This pull request adds translation support and refactors sensor state handling for the MiniBrew integration. The main changes include introducing translation files for user-facing strings, updating sensor classes to use translation keys, and standardizing sensor state values for consistency and localization.

Translation and Localization Support

• Added new translation files strings.json and translations/en.json to provide localized names and states for configuration steps, options, errors, and all sensor entities. This enables user-facing strings to be easily translated and managed.

Sensor Refactoring and Standardization

• Updated all sensor classes in sensor.py to include an _attr_translation_key attribute, linking each sensor to its translation entry for name and state. [1] [2] [3] [4] [5] [6] [7] [8] [9] [10] [11] [12] [13] [14] [15] [16] [17]

• Refactored sensor state values to use standardized, lower-case identifiers (e.g., "online", "offline", "updating", "not_updating", "action_required", "no_action_required", "unknown") instead of human-readable strings. This allows the frontend to display localized states based on translations. [1] [2] [3] [4] [5] [6] [7] [8] [9]

Error Handling Improvements

• Simplified and improved error handling in the config flow by catching all exceptions and logging unexpected errors, ensuring users see a generic error message for unknown failures.

These changes collectively enhance internationalization, maintainability, and user experience for the MiniBrew integration.
