feat(web-console): add current_user info in the top bar

[insmac]

Add user info next to the instance name (if available, not set on the screenshot below).

Will this update after every SQL command?
Just asking because if the user is logged in as my_user, and runs something like:

ASSUME SERVICE ACCOUNT my_service_account;

then my_user has to change to my_service_account.

Basically after the above SQL the user switched to the service account, and SELECT CURRENT_USER() will return the new username.

This will switch back to my_user:

EXIT SERVICE ACCOUNT my_service_account;

not sure how it is decided when to run tables() and update the list of tables on the left panel, but maybe this could work on a similar way.

@glasstiger thanks for your input, good catch! 🥇 👍

In short - no, the current version fetches all the variables in a single query (SELECT instance_name, instance_rgb, current_user) and renders accordingly - this is on load only, but it can be modified as needed.

What I can do easily is to re-run this query once a particular type of query is run in the editor, i.e. we refresh tables() for DDL queries, this can be refreshed as well.

"What I can do easily is to re-run this query once a particular type of query is run in the editor, i.e. we refresh tables() for DDL queries, this can be refreshed as well." -> as discussed, this seems to be a good workaround for now.

Later it is probably worth adding a new type: DCL, which would trigger access control related refreshes, such as current user or list of permissions for the current user.
