Q&A above the receive table to help users troubleshoot

[garyghayrat]

Like the way we explain what a stealth receiver is, like so

I'm thinking where the announcement block # and timestamp is now, we should instead put the question "Where's my fund?" When the question mark is hovered over, we should show the announcement timestamp/block number there with additional explanations. Maybe suggesting them to check subgraph statuses or change their wallet RPC nodes https://support.metamask.io/networks-and-sidechains/managing-networks/how-to-add-a-custom-network-rpc/

Note: currently the timestamp/block number only shows up after a full scan is complete, but with this issue, we should show the question "Where's my fund?" immediately after the first round of scanning is done.
