[CORE-268] Improve Consolidated Spend Report error handling

[calypsomatic]

Jira Ticket: https://broadworkbench.atlassian.net/browse/CORE-268

Summary of changes:

What

This PR:

1. Catches any errors from the spend report query, alerting the user to what the error was instead of crashing the entire page.
2. Discovers any user-owned workspaces that were not included in the spend report, and displays them with N/A values for all spend columns.
3. Adds a note explaining N/A values and linking to support article for setting up spend reports.

Before:

errornotcaught.mov

After:

errorcaught.mov

Why

Testing strategy

[calypsomatic]

I had included endTime and startTime in my test objects because that's what the real-life WorkspaceSpendData responses included, and it broke the build. It seems like it makes sense to match the actual object, so I've added these fields in as optional
