sid:5017050 (Quarantined Files In Endpoint Protection Platform) had no parse_src_ip and no IP present in the raw log, so its threshold's track by_src was tracking nothing meaningfully, and the 5-second suppression window was too short to dedupe a real quarantine burst. Adds a normalization.rulebase rule mapping dhost= to username for CrowdStrike FalconHost logs (validated locally against a real Quarantined Files In An Epp Detection Summary Event sample), and updates 5017050's threshold to track by_username, count 5, seconds 3600 - matching the pattern already used by sibling rules 5012075/5012076.
