feat: HTTP Post credentials, Session Duration Backoff, Update SDK

[danielewood]

Enhancements

Automatic Session Duration Backoff when IDP sets a Session Duration higher than the Role allows.

• Introduced logic to automatically reduce session duration if it exceeds the maximum allowed duration by AWS.
• Ensures smoother authentication when session duration mismatches occur.

Add Latest Role to Popup

• The popup now displays the last assumed role and how long ago it was assumed.
• Helps users quickly verify their current session details (and tell if a role was assumed and HTTP posted).

Add HTTP Post of Credentials

• Introduced an option to send credentials via HTTP POST instead of saving them to a file. This is to overcome an issue in many corporate setting where Downloads cannot be automatically saved and must be individually selected for saving.

Updates

• Updated AWS SDK to 3.734.0
