The settings routes returned the WiFi passphrase, MQTT password and the
login password and PIN in plain text, and the debug log printed them and
the API key. Responses now carry hasPassphrase/hasPassword/hasPin flags,
logs mask the values, and an omitted secret keeps the stored one.
The UI loads secret fields empty and treats a blank field as "keep" while
the SSID or username is unchanged. Clearing a secret without changing the
SSID or username is listed in docs/KNOWN_ISSUES.md.

The RTW decoder formula encKey - 133 was off by one versus the
RTW encoder (which maps command N to encKey N + 132). This caused
every non-My RTW command to decode as the wrong button (e.g. Up
decoded as My, Down as MyUp). Also adds rawCmd diagnostic field to
received frames for protocol debugging.
