Firmware and UI files update separately, so an old index.js can run
against firmware that no longer returns secrets. It sends "" for the
field it can't fill in, which cleared the WiFi passphrase (reboot into
AP mode) or the MQTT password.
The firmware now decides: "" keeps the stored secret, unless the same
request changes the SSID or MQTT username, then it clears it (open
network). /setNetwork compares the settings after applying them, so a
kept passphrase no longer triggers a reboot. The UI cache-buster moves
to 3.0.14d.

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.
