* fix: disable telescope for several commands including migrations

* feat: consolidated, rewritten, and simplified migrations

* tweak: enforce use of postgres, our only supported db

* tweak: use text instead of varchar

this is considered best practice in postgres, as there is absolutely no difference between text and varchar.  if a column size limit is critical, the constraint should be added separately.

* refactor: simplify all types, inline and fix ->timestamps()

* refactor: change all jsonb props to computed using Laravel's Attributes

* refactor: do all metadata rewrites on the fly instead of load time
