chore!: cleanup & lints (#78)

* use `Validators` instead of `PendingValidators` proto

* CI cleanup (fmt, title, etc)

* authz nested message check (recursive)

* add x/POA logger

* add linter settings

* golangci_version=v1.55.2

* Add proto comments

* rm codeowners for now

* disable staking: recursive authz check

* make install in root dir

* params ErrMustProvideAtLeastOneAddress

* validate cachedPower != 0 at a height > 1

* rm migration code

* use single errorsmod

* comments

* keeper test: abstract core setup

* msg_server test tweaks

* add TestRegisterLegacyAminoCodec

* comments

* lint

* minor touch ups

* fix: `BeginBlock` (was modified to sdk.Context)

* move priv msg_server funcs  -> dedicated file

* lint

* simplify pending type to ConvertStakingToPOA

* lint
