improve efficiency for copying mutliple table schemas

[nwoolmer]

Currently, one request is sent per selected table, due to API limitations from the server.

Once the SHOW CREATE TABLE SQL is updated and supports multiple tables, we should update the web console to send a single request for multiple tables at once.

Depends on questdb/questdb#5458

Hey @omsuneri, this requires a server-side work as mentioned above. It is not prioritized yet.

Thanks for your interest.
