* add to link to omni node in the docs

* clean and test both templates locally

* add genesis config presets to runtime

* add genesis config presets to evm template and toml sort generic template

* update abstractions to use runtime genesis presets

* runtime tests for genesis config presets for both templates

* H160 type does not require clone so satisfy clippy
