Add: Koios token support

[kozer]

Fixes #439

Add token support to Koios provider

Proposed Changes

Based on the Koios API specs, Koios can take in the request, an optional auth token. This PR aims to add token support to the Koios provider implementation:

• Added support for authorization tokens in request headers
• Updated the internal methods to properly pass token through the request chain
• Added test coverage for token handling
• Maintained backward compatibility for non-authenticated requests

Implementation Details

During the implementation we made the following changes:

• Added optional token parameter to Koios constructor
• Created getHeadersWithToken utility to handle token header construction
• Updated internal HTTP methods to accept and forward headers
• Added test coverage for both token and non-token scenarios

Testing Instructions

• Run the full test suite to verify all existing functionality remains intact
• Try making authenticated requests through the Koios provider
• Verify that the new test cases for token handling pass
• Check that both authenticated and non-authenticated requests work as expected

Hi, @hadelive!
Is the changeset file correct?
Also I have noticed that some tests are failing. What your team thinks on resolving this ( as I see it happens in other PRs as well ). Should we move to mocking to avoid hitting the network? What do you think?

[hadelive]

No
The errors come from the Maestro provider.

Is there something else that needs to be done so the pr can be merged? Thanks!
