leads: new phone number and an amoCRM lead on every call-button click

The published number becomes +7 927 789-60-71 across all four landings —
`contacts` in each `src/data/content.ts`, plus the fallback messages in the
lead endpoints and `src/lib/lead.ts` that spell it out when amoCRM is down.
The `legacy/` reference pages keep the old number: they are the visual
originals, not something that ships.

Tapping the phone button now also creates a lead. It cannot reuse the form
path: a click carries no name and no number, so `callClickSchema` in
`shared/lead.ts` validates the tracking data alone, `LeadService.submitCallClick`
creates a contactless lead tagged `клик по телефону`, and `AmoClient.createLead`
takes an optional `contactId` for it. The mapper's field/note split moved into
`collect()` so both lead kinds share it.

The browser fires this with `sendBeacon` (falling back to `fetch keepalive`),
because the same click hands the page to `tel:` and a plain fetch would be
cut off mid-flight. Duplicates are held down from both ends: one lead per
browser session on the client, four per IP per 30 minutes on the server.

+Кнопка звонка (в футере и в модальном окне «Перезвоним вам») помимо набора номера отправляет
+`POST /api/leads/fitness-centers/call` — маячком `navigator.sendBeacon`, чтобы
+запрос пережил переход браузера на `tel:`.

+номера, известен только факт клика. Имя сделки — «Звонок с сайта — Recovery Zone»,
+тег — `клик по телефону` (плюс `AMO_LEAD_TAGS`), страница и `utm_*` идут в поля
