Persist commissioning packages on refresh

Aim of the PR

This PR fixes AB#208958.

The goal of this PR is to make sure the commissioning packages are persisted and not deleted on refresh of the page.

Implementation

Several changes have been made to achieve this:

• Instead of cleaning the triplestore and list of commissioning packages on mount, we get the packages from the triplestore.
• When the app is started and an initial commissioning package is created, the color and name is saved to the triplestore.
• When a user creates a new commissioning package, the color and name is saved to the triplestore.
• Instead of getting just the node Ids from the triplestore, we now get node Id, name and color.
• Added a new "getAllCommissioningPackages" that is called when the page is refreshed. This method gets all commissioning packages, including the name and color.
• Add SelectedInternal as type a node can have. This is so that we can save which node was clicked as the internal boundary.

Type of change

• Bug fix
• New feature
• Breaking change
• This change requires a documentation update

How Has This Been Tested?

This has been tested by running the demo and testing the UI.

Additional Changes

I deleted some unused code from Triplestore.ts to clean up the file. Let me know if the code that has been removed should be kept there!
