Fixes: FRMW-2742
In this PR, we fix the build output of the backend source code, which eliminates a lot of magic between the development and production environments.
Right now, we only compile the source files from the `src` directory and write them within the `dist` directory.
**Here's how the `src` directory with a custom module looks like**
```
src
├── modules
│ └── hello
│ ├── index.ts
```
**Here's the build output**
```
dist
├── modules
│ └── hello
│ ├── index.js
```
Let's imagine a file at the root of your project (maybe the `medusa-config.js` file) that wants to import the `modules/hello/index` file. How can we ensure that the import will work in both the development and production environments?
If we write the import targeting the `src` directory, it will break in production because it should target the `dist` directory.
## Solution
The solution is to compile everything within the project and mimic the file structure in the build output, not just the `src` directory.
**Here's how the fixed output should look like**
```
dist
├── src
│ ├── modules
│ │ └── hello
│ │ ├── index.js
├── medusa-config.js
├── yarn.lock
├── package.json
```
If you notice carefully, we also have `medusa-config.js`, `yarn.lock`, and `package.json` within the `dist` directory. We do so to create a standalone built application, something you can copy/paste to your server and run without relying on the original source code.
- This results in small containers since you are not copying unnecessary files.
- Clear distinction between the development and the production code. If you want to run the production server, then `cd` into the `dist` directory and run it from there.
## Changes in the PR
- Breaking: Remove the `dist` and `build` folders. Instead, write them production artefacts within the `.medusa` directory as `.medusa/admin` and `.medusa/server`.
- Breaking: Change the output of the `.medusa/server` folder to mimic the root project structure.
- Refactor: Remove `Symbol.for("ts-node.register.instance")]` check to find from where to load the source code.
- Refactor: Use `tsc` for creating the production build. This ensures we respect `tsconfig` settings when creating the build and also perform type-checking.
