Tip: show modal instead of toast when timeout

## Issue
The toast wasn't good enough as the user might miss it and attempt to re-send.

## Change
- Change the tip timeout from Toast to Modal.
- For the case of Comments, add additional info about being unable to re-link the txid to the comment for now. Not really useful to the user, but better than nothing.
