Add the security section of the settings dialog

[theosiemensrhodes]

This should be in the src/components/settings/security-settings-content.tsx file. Which is viewable in the settings overlay when you are on the security tab.

This part should allow the user to:

• Logout
• Log out all sessions across devices
• Change their password

These should all be able to be done via the better-auth frontend api.

• Logout and Change password docs
• Revoke all sessions docs

There is no design for this, however you can take inspiration from the shadcn design system.
