fix(deploy): polish subdomain field UI

- Remove "Automatikusan generálva" badge from domain field (it's not
  generated, it's the customer's configured domain)
- Shrink subdomain input width (8rem) so the .domain suffix appears
  directly next to it on the same line
- Suppress redundant "Az alkalmazás aldomainje" description hint for
  subdomain fields (the warning hint is sufficient)
