Four x_fc_* fields on res.config.settings backed by ir.config_parameter:
retention_days (default 365, 0 = forever), alert_threshold (5),
alert_window_min (15), alert_enabled (True). New "Login Audit" block
on the General Settings page (gated by base.group_system on the block,
NOT on the inherited view record per CLAUDE.md rule #11).
CLAUDE.md gotchas added during this task:
#5 Boolean config_parameter fields don't round-trip "False" as a
string — IrConfigParameter.set_param deletes the row on falsy.
Test with assertFalse, never assertEqual(..., "False").
#6 ir.ui.view uses group_ids (Odoo 19 rename mirrored from res.users).
Setting groups_id on an ir.ui.view record raises ValueError at
install. (The XML attribute groups="..." on inner nodes is
unrelated and still works.)
