we no longer resolve handles from DIDs at the handlers, we do this dynamically when rendering the templates. EmailToDidOrHandle did not follow this pattern. there were a few negative side effects from this: the `tinyAvatar` helper requires that the input be a DID; and not a handle. when a handle is passed, it results in a different default color for users without profile pictures; resulting in different colors in repo-log versus, say, the topbar.
