[Lake][Validations] Lake validation and info logic should remain inside of lake module, not webapp module

[idiom-bytes]

Is your feature request related to a problem? Please describe.
Core lake module and CLI tool was moved outside of the module, and is no longer serving my own requirements. Rather, webapp/frontend modules should be using engine interfaces, not moving code around to serve it's own modules.

Describe the solution you'd like
Keep core lake module and engine logic inside of /pdr_backend/lake/ module
/lake/ -> all core logic, objects, and interfaces
/lake_info/ -> whatever it needs to serve the data/results to the web app

core logic/components/APIs/cli inside of "core engine modules" should not be moved to the webapp/frontend modules
