Update XMTP-JS SDK docs to document 4 dbPath value types, including a function callback, in agents and chat-apps ClientOptions for @xmtp/node-sdk@4.1.1

• Add a commented example showing dbPath as (inboxId: string) => string in Client.create options in create-a-client.mdx and create-a-client.mdx
• Update ClientOptions docs to state there are 4 dbPath value types and include the function signature (inboxId: string) => string in both files

📍Where to Start

Start with the ClientOptions type section in docs/pages/agents/core-messaging/create-a-client.mdx, then review the parallel updates in docs/pages/chat-apps/core-messaging/create-a-client.mdx.
