chore(web): drops alignInputs, hideInputs 📴

A follow-up to #7343.

I could've included it as part of that one, but these changes were easy enough to isolate and may be worth some discussion in isolation, given the old waitForFonts method. It is my understanding that waitForFonts existed to prevent a "flash of unstyled content" effect on touch-alias elements that would otherwise result from asynchronous font loads.

After a bit more investigation into any possible extra avenues for cleanup, I've documented #7387. It's not 100% straightforward, so it should probably be left out of this PR.
