reinitiate manifest array field state on refresh

[dpgraham4401]

🚀 Feature Request

To enhance the UX, it's annoying that we have to re-add the transporters and waste lines every time the manifest form refreshes for a draft manifest (which happens often in a development environment). Currently, the generator and TSDF are stored in a URL parameter and retrieved on refresh.

We could also implement a similar feature for transporters since they are also retrieved from the haztrak db, waste lines represent a more unique challenge since we don't save waste lines to the database unless they're associated with a manifest (which does not exists until the manifest has been saved).

Options:

1. use the browser API to store waste lines.
2. Start saving waste lines to the haztrak db every time a new waste lines is created/updated.
   • I'm not a fan of option 2 because it would create orphan waste lines. These could be cleaned up periodically but the risk of deleting waste lines that are still attached to a manifest is present.
   • It's additional network traffic
