/**
 * One profile groups a set of contacts and prescribes how Lettem In answers calls
 * from any of them.
 *
 * @param dtmf one of 0-9, *, #. Default "9".
 * @param audioDurationMs duration of the uploaded audio in milliseconds. Set when
 *        an audio file is uploaded; used to size the auto-hangup timer dynamically.
 *
 * Constraints:
 *  - A contact key belongs to at most one profile.
 *  - audioFile is the filename stored on the Teensy SD card (e.g. "p_abc.wav").
 *    Null = no audio file selected (behavior must be REJECT or DTMF).
 *
 * Special pseudo contact keys:
 *  - "ANONYMOUS"        — caller with no number / blocked caller ID.
 *  - "SPAM"             — STIR/SHAKEN attestation failed.
 *  - "NOT_IN_CONTACTS"  — caller number present but not saved as a contact.
