Reduces the amount of boilerplate to render the UI and makes it easier to respond to state changes (e.g. machine getting authorized, netmap changing, etc.) Preact adds ~13K to our bundle size (5K after Brotli) thus is a neglibible size contribution. We mitigate the delay in rendering the UI by having a static placeholder in the HTML. Required bumping the esbuild version to pick up evanw/esbuild#2349, which makes it easier to support Preact's JSX code generation. Fixes #5137 Fixes #5273 Signed-off-by: Mihai Parparita <mihai@tailscale.com>
