feat : add authorization bearer token support for protected APIs

[NAVIN0507]

Summary

This PR adds Authorization (Bearer token) support to the Motia Workbench request trigger, allowing developers to test protected APIs that require authentication. The implementation preserves header casing, automatically prefixes Bearer when missing, and safely ignores inactive or invalid headers.

Hey @NAVIN0507, thank you for this contribution! Adding Authorization Bearer token support to the Workbench request trigger is a great feature — being able to test protected APIs directly from the Workbench is something developers will definitely appreciate.

However, I wanted to let you know that we're currently working on a major architecture change that will fundamentally change the internals of how Motia handles request routing, authentication, and API interactions.

Because of the depth of these changes, the dashboards and their request handling will look quite different once the new engine is in place. We'd love for you to revisit this contribution at that point — your understanding of the auth flow and how developers interact with protected APIs will be really valuable in shaping the experience on the new architecture.

I really appreciate you taking the time on this and seeing all your contributions!

Also I may have mentioned this previously but to be the first to know when the architecture change is released please add your email to this form: https://forms.gle/24iCHL9yAk1i6LDc6
