Initial work to integrate annotation page components and global store

[jarmoza]

Integrating the recent additions to the annotation page with the elements of the global store.

• columnToCategoryMap and dataTable are now used by annotation page components.
• dataTable.original is read by annotation page components and when annotation changes are made via writeTable on annotation.vue changes are made to dataTable.annotated
• writeColumn was rewritten to call the unlink column with category action from the store
• A fix was put into place where to align the name of the assessment category on the categorization page with the annotation page. It's called 'Assessment Tool'.
