Fix migrations

3 changes:

1. Changed ids and foreign key columns to use `bigint` instead of `int`. Rodauth (and Rails) now uses `bigint` columns for the ids, so using `int` for the foreign keys doesn't work.

2. Added missing `index` keys for some unique fields to fix `ArgumentError: Unknown key: :unique.` error.

3. Rails now uses precision 6 for `datetime` fields by default, so the default values must also specify that. See [this](janko/rodauth-rails#159).
