Run lint to proto files

[foxytanuki]

Ran buf lint and got 290 errors across a bunch of types:

• PACKAGE_DIRECTORY_MATCH
• COMMENT_MESSAGE
• FIELD_LOWER_SNAKE_CASE
• IMPORT_USED
• RPC_RESPONSE_STANDARD_NAME
• COMMENT_RPC
• COMMENT_ENUM
• COMMENT_ENUM_VALUE
• ENUM_VALUE_PREFIX
• ENUM_ZERO_VALUE_SUFFIX
• COMMENT_ONEOF

Not convinced we need to fix every single one. Thinking some could be skirted around with config tweaks. Still, I am willing to dig into which ones actually need some work and get cracking on those fixes.
