FIXES: FRMW-2727
MikroORM (with version 5.9) has [hardcoded the TypeScript module](https://github.com/mikro-orm/mikro-orm/blob/5.x/packages/core/src/utils/ConfigurationLoader.ts#L138-L139) system to `commonjs`, which makes it incompatible with the module system we are using, ie `Node16`.
So, in order to continue using the Mikro ORM CLI within our modules, we will have to monkey-patch the block of code responsible for configuring `ts-node`. However, the monkey-patching must be done before their CLI gets booted.
As a result of this, we have to create a wrapper CLI on top of Mikro ORM CLI that performs the following steps.
- Monkey-patch the relevant code
- Register Mikro ORM CLI as the second step.
Due do this, we will have to use this new wrapper CLI within the modules, which is exposed as `medusa-db`. Maybe, `medusa-db` is not a great name, so please send your suggestions.
**What**
Update the `MedusaService` class, factory and types to remove the concept of main modules. The idea being that all method will be explicitly named and suffixes to represent the object you are trying to manipulate.
This pr also includes various fixes in different modules
