Add a "Copy chat link" button inside conversations

Problem
Today, to share a specific conversation with a teammate, we have to find the chat ID and manually build the URL (https://console.periskope.app/chats/[chat_id]), adding @c.us for individual chats or @g.us for groups. This works, but it's slow and error-prone, especially for people on the team who don't know the URL format.

Suggestion
Add a "Copy link" button (or an option in the conversation menu) that copies the direct URL of the current chat to the clipboard with one click.

Use cases

• Sharing a conversation with a teammate or manager for escalation or review

• Linking the chat in internal tools (Slack threads, Notion cards, support tickets) so anyone can jump straight to the context

• Speeding up handoffs between team members handling the same client or group

Expected benefit
Faster collaboration and fewer mistakes when referencing conversations, without needing to know the chat ID format.
