consolidate apmt.day with appointment.day routes

Is your feature request related to a problem? Please describe.
a user notes that "appointment" being quite a long word to type, [they] will try to use apmt.day to go to appointment.day; but we currentl redirect apmt.day (with or without trailing slash) to appointment.day/user/ which goes to a "Sorry, this page could not be found." instead of the splash page. also applies to the empty/root path, which results in an error page. If it's not too difficult it would be neat to redirect https://apmt.day/ to https://appointment.day/.

Describe the solution you'd like
apmt.day should go to appointment.day. We can look at other routes that we may need to consolidate

Right now its setup as a redirect to /user/

appointment/tofu/modules/services/backend-infra/main.tf

Line 120 in 43e5993

shortlink = {

Once we move the frontend routing back to our application it should be easy to conditionally redirect based on no path (to appointment.day) vs path (for /user/)
