Add Option for Riders to Update Password from Rider App

Is your feature request related to a problem? Please describe.
Currently, there is no option in the Rider app for users to update or change their password. This can be problematic if a rider wants to enhance account security or has shared credentials.

Describe the solution you'd like
Provide an option within the app settings or profile section that allows the rider to update their password by entering the current password and setting a new one.

Describe alternatives you've considered
An alternative would be relying solely on the "Forgot Password" flow, but this is not ideal for users who are already logged in and want to proactively change their password.

Additional context
Allowing password updates within the app improves account security and gives users more control over their personal information.

The issue names the Rider app settings or profile section and the existing Forgot Password flow, but no files or tests. Start by locating those entry points and determine how authenticated password changes are handled; done means riders can enter their current password and a new password from the app.
