Feat/mcp authentication

[Kawron]

This PR implements support for TLS and token based authentication for both SC4S API and MCP Server.

Both aps have different implementation though they are quite simillar. So I recommend reviewing first package/sbin and then mcp_server folders. I decided not to write a single fit all implementation because:

1. Those are two different aps, that can are independent of each other and can are deployed separately. If we would like to have shared implementation they would have to import each other
2. The are small differences between those two, e.g. mcp server token authentication extends FastMcp class for authentication and they use two different web servers: uvicorn vs gunicorn
3. Keeping implementation seperate give us more flexibility
4. It should be fairly easy to extract some of the methods to common util package that will be imported by both aps, if the cost of maintaince increases
