Durable login audit for Odoo 19 (westin-v19). Captures successful and
failed authentications via _update_last_login / _check_credentials /
_login overrides, surfaces history on res.users as a smart button +
"Login Activity" tab (admins-only), async geo-enriches IPs via ip-api.com
through network_logger, 365-day retention with daily GC cron, and
emails Settings admins on N consecutive failures for the same login
within a configurable window.
Motivation: a spot audit of GSA Accounting (uid 63) showed Odoo's
res_users_log keeps only one row per user (rest is GC'd), /var/log/odoo
is empty (warn-level stdout logging), and the container json log
rotates within days — leaving no durable login trail.
