Initial import: eCW Charge Validation bot and results Portal

Snapshot of the working project as of 2026-10-23 (local 2d4d4fc), one
commit with no earlier history: the tracked files were de-identified
first (synthetic claim ids and patient data only; see Context.md
section 7). Credentials, run logs, screenshots, claim reports and client
workbooks are gitignored and not included.
