Block for inserting/upserting THX attributes into the thx table

This block is responsible for inserting or updating THX-related records in the thx table using the same database configuration as db_push_v1.

Table DDL

The following DDL illustrates the thx table structure (Postgres style, conceptually compatible with DuckDB for tests):

-- creating thx table
CREATE TABLE IF NOT EXISTS thx (
    application_key TEXT PRIMARY KEY,
    application_timestamp TIMESTAMP NULL,
    digital_id_first_seen TEXT NULL,
    summary_risk_score TEXT NULL,
    cpu_clock TEXT NULL,
    true_ip_first_seen TEXT NULL,
    ssn_hash_first_seen TEXT NULL,
    account_email_attributes TEXT NULL,
    tps_ip_latitude TEXT NULL,
    tps_ip_longitude TEXT NULL,
    account_telephone_first_seen TEXT NULL,
    account_login_first_seen TEXT NULL
);

CREATE INDEX IF NOT EXISTS idx_thx_application_key ON thx(application_key);
CREATE INDEX IF NOT EXISTS idx_thx_application_timestamp ON thx(application_timestamp);
