"""Settings-secret redaction for GET /api/settings (#832 follow-up).
GET /api/settings used to ship the DECRYPTED config to the browser — every API
key, token, and password in cleartext. redacted_config() masks configured
secrets with a sentinel; set() refuses to let that round-tripped sentinel
overwrite the real value. Together: secrets never reach the client, and saving
an unchanged form never clobbers them.
ConfigManager.__init__ touches the DB, so these build instances via __new__ and
set config_data directly — the methods under test only read/write that dict.
