refactor: attempt to rename grpc so v is trailing

[matt2e]

WIP
Imports are broken at the moment, it seems that it wants us to refer to each imported reference fully (ie xyz/block/ftl/schema/v1/schema.Ref rather than schema.Ref

I think I've figured out what the import rules are. If you have two packages:

xyz.block.ftl.console.v1
xyz.block.ftl.schema.v1

Ad you're trying to use xyz.block.ftl.schema.v1.Schema in the console proto, you'd need to reference it like so:

schema.v1.Schema

That is, it will look for a common relative root.

Doing this while #3417 is open is just going to cause more pain. I'll wait for that to come in and redo these changes
