Aider: rename all user visible instances of "threads" to "smiths"

[tomasmcm]

Currently this app is called "threads", we want to call it "smiths" instead. Make sure to rename all user visible instances of "threads" in the app. First check the components files that are being used to build the UI and look for the word "threads" in strings that end up in the final HTML, then change those to "smiths".
