Detailed Description

Singleton giving access to the Vortex board persistent-storage namespaces.

Initialization runs before communication managers so calibration or board identity can be read early. Namespaces (≤15 chars per ESP-IDF):

• "vortex" — general application key-value
• "vortex_cal" — calibration / factory tuning blobs
• "vortex_cfg" — structured device configuration
