Add Option for Riders to Update Password from Rider App

Nobody has claimed this yet.

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.

Start at the Rider app's settings or profile entry point and compare it with the existing Forgot Password flow. Trace how the current password and new password are handled, then verify that signed-in riders can submit the change and receive appropriate success or error feedback.
