feat: wrap the store around AdsProvider

[Copilot]

What problem is this solving?

Integrates VTEX Ads into Store Framework via AdsProvider wrapper. Part of the Ads Frictionless Integration RFC.

Key change: ads are now hydrated client-side, enabling CDN cache hits for product data (previously uncacheable due to real-time auction responses).

Changes:

• VTEXAdsProvider: wraps store content, provides ad context using publisherId from store settings
• Fetches user session data client-side for ad targeting
• Uses @vtex/ads-react SDK to request and merge ads with product data
• Adds publisherId setting to manifest schema (replaces fetchSponsoredProductsOnSearch)

How to test it?
