See which language each conversation's chat panel used

Every conversation now records which language its chat panel resolved to: the same language covered by the new per-site language settings and conversation starters. This is the chat surface's own language, not a guess at what language the shopper actually typed in or what language the assistant replied in.

• The Conversations grid gets a Language column, and a Filter by language dropdown (any enabled language, or Unknown) alongside the existing Channel, Agent, and Feedback filters.
• A conversation's own detail page shows its Language in the Details rail, next to agent, version, channel, and created date.
• Conversations recorded before this shipped show as Unknown: they were never guessed, so there's nothing more precise to show.

The Conversations report gains two new cards. A Language distribution card ranks this period's conversations by their recorded language (with an Unknown bar when applicable), and an Impressions & clicks card shows total recommendation impressions and total clicks on in-chat product cards over the same period. Both scope to real shopper traffic only (Hosted and Web), the same way every other metric on this report already excludes Playground testing.
