hotel: apply the v7 design and add the callback dialog

Ports legacy/hotel v7 into the React landing.

- Copy: nav is Экономика / Для гостя / Интерьер / Сервис, and «Интерьер»
  now comes before «Сервис». The hero keeps one button and gets the
  2 500 ₽ / 600 000 ₽ / 7,2 млн ₽ facts. New headings and leads for the
  interior, service and request blocks. Session lengths 10–15 and 30–60
  min, area 12–36 m².
- Calculator counts sessions and gains the ЭкзоКлиник benchmark and a
  «Получить консультацию» button.
- Request form: company and email are optional. The server schema
  already treats them as optional.
- v8 phone type scale (≤620px), a 380px `micro` step, and a `slim`
  (≤640px) variant. The max-width variants are now declared widest first,
  so the narrower one wins where two apply.
- The market charts' SVGs stay inline, as in the mockup.

The header «Звонок» button opens the «Перезвоним вам» dialog from the
fitness landing (name, phone, consent). The server accepts form
'callback', names the deal «Обратный звонок — <имя>» and tags it
«обратный звонок». The phone link inside the dialog still reports a call
click.

With Inter substituted into the mockup, the page text matches it line for
line (except the fixed «2025–2026 гг.» typo), and every section height
matches at 360–1440 px.
