feat: dynamic business hours status on Contact page

Replace hardcoded 'Open now' text with automatic Open/Closed status
based on user's timezone. Uses Intl API to detect timezone and compare
against business hours (Mon-Fri 10AM-6PM IST). Status updates every
60 seconds. Includes aria-live for accessibility.
