• Created CreatePoolLiquidityBootstrappingFixedPriceInput and FixedPriceLBPParams types

A couple of queries to address and please add a ChangeSet for the release.

We recently updated CI to skip integration tests which have been quite flaky. I added some AI generated unit tests so we have a bit more CI coverage. Would be great if you could double check them to see if they make sense or if you have any suggestions to add more.

I have replaced it with CreatePool here so that the below edge cases get passed through the inputValidator
