### The Feature

I would like LiteLLM Admin UI and management APIs to support user self-service password change and a standardized reset password flow.

Desired behavior:

1. Logged-in users can change their own password from the user menu. 2. Password change requires current password verification. 3. Admins can trigger a reset password flow for a user. 4. Onboarding can support a reset-password-required state. 5. Password update time can be recorded for audit.

This should apply to LiteLLM-managed users where password-based login is enabled.

### Motivation, pitch

In enterprise deployments, LiteLLM Admin UI may be used by many internal users, not only platform administrators.

Users often need a standard way to change their own password without asking an admin or directly modifying the database. Admins also need a clean reset password flow for onboarding and account recovery.

Adding this as a standard feature would reduce local UI patches and make LiteLLM easier to operate in internal enterprise environments.
