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.

+# Salud eCW Charge Entry Bot — login phase.
+# .env is parsed by src/ecw_bot/settings.py directly, so python-dotenv is not
+# needed — these machines are locked down and every dependency is an approval.
+# The tests run on plain asserts for the same reason: no pytest.
+# Everything else (imaplib, email, ssl, ctypes) ships with the stdlib.
