Peter Woolery 2226c1b4ca fix(tools): validate flash_device.py HMAC secret format before flashing
--hmac-secret accepted any string and passed it through to NVS, silently
producing a device that cannot authenticate to the server. Reject anything
that isn't exactly 64 hex characters (32 bytes) before generating the NVS
image. Auto-generated secrets are validated too as a defensive check.
