feat: show the name of the db file on side barl by default expand list of tables

[wliao008]

1. I think it'd be helpful to show the name of the db file that's passed in (or the default name if not) in place of Tables, so if I pass in

$ SQLITE_NAME=/path/to/mydata.db go run main

It will show mydata.db there, otherwise show data.db.

2. Could we always show the list of tables, and remove the collapsable toggle?

@wliao008 Can you assign this to me?

[wliao008]

@nikzayn thanks for the interest! assigned.

mydata.db

This seems okay, right or should I remove Tables as the header?

@nikzayn please read @wliao008's requirement: "show the name of the db file that's passed in (or the default name if not) in place of Tables"

The table dropdown will only show the table names, not the database filename.
