Update sample project to use library version 0.3.0

[JsFlo]

• Updates sample project to use library version 0.3.0
• Fixes ktor example by using .start(wait = True) similar to the plain config example
• updates function names to conform to the kotlin style guide per the contribution guidelines (only test function names should use the backticks with spaces)

Motivation and Context

I realize there's not technically an issue on this but wasn't sure if a sample project update needed one but I wanted to try this library out but the sample was slightly outdated and the ktor example wasn't working so I updated it for my tests and figured I could put a PR to update in the project. Feel free to close this if this isn't appropriate as I'm not sure the procedure with sample updates

How Has This Been Tested?

I focused on the KTOR and plain config examples and in those cases I was able to use a basic SSE python client to make the connection get session/messages list tools. I updated the stdio example with the new library and that seems to work as before though I don't know how that's used as it immediately closes connection but that's the same behavior before and after my changes.
