Convert hotel landing to React + Tailwind v4 with amoCRM lead capture

Ports the single-file ЭкзоОтель page to the same architecture as the fitness
landing: Vite + React 19 + TypeScript + Tailwind v4 on the client, Express 5 for
the /api/leads/hotels endpoint, zod schema shared between the two.

The original page is kept in legacy/index.html as the visual reference. Its 15
inlined base64 images are extracted to files (the 1 MB HTML becomes ~318 KB of
JS plus assets loaded on demand), and its text is reproduced line for line —
verified with an innerText diff. Section heights stay within 0.6% at 375 and
1440 px; the drift comes from Inter actually loading, which the original asked
for but never served.

Three deliberate departures, documented in the README:
  * eyebrow and lead in the CTA block were dark teal on navy (3.4:1); they now
    match the other dark sections
  * hero fact values overflowed their 80px column into the label below 430px
  * "2025–2026г.." typo in the market source note

Leads reuse the fitness amoCRM integration: contact lookup by phone in every
spelling, deal in the first stage of pipeline 10980758, account fields matched
automatically with the rest written to a note. Rate limit, honeypot, and a
localStorage fallback so a lead survives the CRM being down. Vite runs on 5174
and the API on 3001 so both landings can run at once.
