The log sanitizer only used regex patterns, missing arbitrary user-chosen strings (printer names, usernames). Tasmota smart plug credentials were logged verbatim in URLs by httpx. - Make _sanitize_log_content() database-aware: query Printer names/serials, User usernames, and Bambu Cloud email for exact-string replacement (longest-first, skip <3 chars to prevent over-redaction) - Fix serial regex leaking first 3 chars (remove capture group partial redaction), add case-insensitive flag - Move Tasmota credentials from URL-embedded (http://user:pass@host) to httpx auth= parameter so they never appear in logs - Add URL credentials regex as defense-in-depth for user:pass@ in logs - Add 'username' and 'path' to settings sensitive_keys filter (catches smtp_username, slicer_binary_path in support-info.json)
