When disconnected from a DB, pop-up should allow to re-connect

**Is your feature request related to a problem? Please describe.**
I don't save password on my connections.
I have a dozen sql editor tabs open, each with its own connection.
Every day all of my connections disconnect (when the computer sleeps) and I have to start my day by manually connecting to each data source.

**Describe the solution you'd like**
When I run a query in an Sql editor for a disconnected DB, I get the following pop-up:

Would be **really** useful to have a "Reconnect" button there, as if I double clicked on the connection itself.

The issue names no files or tests; start by reproducing the disconnected SQL editor popup after a query is run. Trace the existing connection action triggered by double-clicking the connection, then determine how the popup can expose the same reconnect path. Done means the popup offers Reconnect and restores the disconnected data source.
