Yucheng Zhu 52f3ff13f0 feat(proxy): limit repeated failed Admin UI sign-in attempts
The Admin UI sign-in endpoints accept an unbounded number of password attempts.
All three call authenticate_user, and none of them keeps any record of how many
times a given caller has already been refused, so a misbehaving or misconfigured
client can retry indefinitely at full speed.

A LoginThrottle is now a required argument to authenticate_user, so the accounting
lives at the one function all three endpoints share and a fourth endpoint cannot be
added without deciding what to pass. Failures are counted per username and source
address over a fixed window and further attempts are refused with 429 and a
Retry-After header. The check runs before the database lookup and before the
password comparison, so a refused caller does no further work.

Only genuine credential rejections count. Configuration errors do not, a refused
attempt does not extend the window, and a successful sign-in clears the bucket.
The username is case folded because the user lookup is case insensitive, so casing
cannot multiply the allowance. Both credential rejections now return one identical
message. SSO is unaffected; it never calls this function.

max_failed_login_attempts (10) and failed_login_window_seconds (900) are read from
config.yaml, with LITELLM_DISABLE_LOGIN_RATE_LIMIT to turn the accounting off. They
are deliberately not database backed, so editing YAML always wins and an operator
refused by a bad value can recover.
