Revert "We have had errors reported due to migrations breaking and are reverting"
This reverts commit 8b46f14744.

It corrects the reason for the revert:

We rely on SafeMigrate existing cause we call it from migrations,
Zeitwerk will autoload it.

Instead of previous pattern we explicitly bypass all the hacks in
production mode.

We need to disable SafeMigrate cause it is not thread safe.

A thread safe implementation is possible but not worth the effort,
we catch the issues in dev and test.

DEV: only enable SafeMigrate in development and test
SafeMigrate outputs text when we detect attempts to unsafely drop tables
and columns

It is unfortunately not thread safe

This is not needed in production as we would have already caught it by then
in our test suite.

Sam Saffron 30990006a9 DEV: enable frozen string literal on all files
This reduces chances of errors where consumers of strings mutate inputs
and reduces memory usage of the app.

Test suite passes now, but there may be some stuff left, so we will run
a few sites on a branch prior to merging

Sam 6a3c8fe69c FEATURE: protect against accidental column or table drops
Often we need to amend our schema, it is tempting to use
drop_table, rename_column and drop_column to amned schema
trouble though is that existing code that is running in production
can depend on the existance of previous schema leading to application
breaking until new code base is deployed.

The commit enforces new rules to ensure we can never drop tables or
columns in migrations and instead use Migration::ColumnDropper and
Migration::TableDropper to defer drop the db objects
