Default db migration behavior should be to use migrations from current source

[akajla09]

Describe the bug
Currently, the default for go-migrate is to pull db migrations directly from Github (main branch) and run them (including with the autoMigrate flag). This means that you could potentially have a mismatch between the migrations being run and the server code if it is not up to date.

Expected behavior
Only the migrations up to the current version of source (whether built locally or pre-built) should run. This might mean packaging the migrations along with the binary.
