Commit 4 renamed `[oauth_single_audience]` → `[login_flow]` via a global
sed pass, but ADR-025's example settings.toml already had a `[login_flow]`
section just above the `[keycloak]` block. The rename produced two
back-to-back `[login_flow]` headers with identical contents — TOML parsers
either reject the file or silently override, and a reader copying the
example would land on either outcome.
Dropped the now-duplicate second `[login_flow]` section (the renamed one).
The earlier `[login_flow]` section retains the same content + a comment
explaining the ADR-022 derivation, so no information is lost.
