feat(methods): complete codeChannels examples and minimize scopes

Add examples for the remaining codeChannels methods (archive, rename,
setProperties, setCommands, listViews, removeView, getCanvas,
setCanvasContent) and trim the manifest to the single code_channels:manage
bot scope the methods require.
