Move to Flickwerk

[jarednorman]

Desired Behavior

"Patches" should be loaded via Flickwerk.

Current Behavior

"Overrides" are loaded via custom loading code in config/application.rb. There's a bug where they get loaded twice.

Additional notes

• Override loading issue: https://github.com/solidusio/solidus/issues/4877
• There are only two "overrides" in this project, so this should be a trivial change.

@senemsoy Do you want to tackle this?

[senemsoy]
