fix: таймаут 15с на все fetch в clients.js — кнопки больше не висят

- _fetchWithTimeout() — единый fetch с AbortController
- saveClientNote, fetchClientNote, fetchClients, fetchMeasurements
  теперь через таймаут вместо бесконечного ожидания
- При таймауте показывает 'Сервер не отвечает — попробуйте ещё раз'
- Версия clients.js: 20260518e
