ssc init should default to port 1433

[Jaxelr]

Describe the Feature

When running ssc init currently the default value for port is undefined, this causes the field to be NaN on display and Null on creation.

As i understand it, it would be a more pleasant UX to default to port 1433, which is the usual sql server default port.

Suggested Solution

The suggested solution is to on line 62 of the init.ts command file switch to 1433 the default value:
