Multi-NAS has arrived + Bugfixes

Important

This update contains BREAKING CHANGES:

• All users: You may need to delete and re-adopt your NAS once in Devices and Services > Ugreen. All data will be kept, and all entities will automatically be re-created as long as you keep the default NAS unique name as ugreen_nas. Please make sure you use the 'Add' button offered by autodiscovery instead of manually adding the NAS.
• Pre-made dashboard users: Please run again through the Wiki page and replace your existing code with the new one to get all the new features.

👉 Changes: For end users

• The integration can now handle multiple UGreen NASes simultaneously (any models).
• The pre-made dashboard has been adjusted accordingly. It now also serves default pics for all NAS models in www/community/ugreen.
• Config flow has been amended to control Multi-NAS settings and individual display options for each NAS on the pre-made dashboard.
• Dashboard sort criteria for tiles and disks now working properly (both had wrong order in specific configs).
• Cache general info and cache disk entities / tiles have been reworked.
• Fixed an issue where the NAS would not wake up when pressing the Wake On LAN button.

👉 Changes: For fellow developers (internal changes)

• Add local brand icons and logos.
• Add further local languages for config flow (fr, es, it).
• Update and amend local translations.
• Add necessary consts for Multi-NAS and Dashboard.
• Create select.py and text.py for Multi-NAS Dashboard features.
• Implement changeable entity_prefix for Multi-NAS.
• Remove obsolete const_device_name.
• Add default picture files for Lovelace frontend.
• Implement automatic copying of picture files to /local/community/ugreen (=/config/www/community/ugreen).
• Further harden autodiscovery against double detection.
• Implement 'forgotten' cache summary entity.
• Move old www/pictures repo path to .deprecated.
• Bump version to v2026.03.1.
