Problem: Package details summary area does not show useful information

[fiver-watson]

Describe the bug

Currently the Summary area on the Package details page is mostly ignored by users, and does not provide useful at-a-glance information. Example issues include:

• Assumes all packages are AIPs, and highlights AIP creation details - this means the area is useless if viewing information about SIPs, PIPs, or DIPs - or even AIPs that were created outside of Enduro but are still stored and registered in the system
• Actual Package details area is not being populated - currently object count and package size are always "N/A"
• For many clients who are just creating AIPs and storing them (i.e. just running 1 workflow), the current page's "Workflow status" and "Last workflow status" are just duplicates
• Other potentially useful information is not included on the page

Expected behavior

Propose the following changes:

• Make the left side "Package details" - do not associate it with only AIPs, or with AIP creation
• Begin storing and displaying useful information about the packages, such as size, object count, date of ingest, date of storage, etc
• Move the (still unimplemented) "View metadata summary" button below the package details
• Move the download button to the Location area
• Change the previous "Package details" section on the right column to a "Last preservation action" summary area
• Include the last workflow's Workflow name, status/outcome, start and end times, and workflow ID (for troubleshooting if needed) there
