Merge train 4843-2b (CI only; not for merge)

[erikdarlingdata]

Merge train, not for merge. This PR exists only to run CI once on dev plus the squash of each PR below, in this order. When it is green, each PR is squash-merged by itself in the same order, and dev's final tree is checked against this branch's tree. Then this PR is closed unmerged. It replaces #5126, which went red on two test-harness crossings between its PRs. Those crossings are now fixed in #5120 and #5123.

Part of #4843 (and #5097 for the stall-probe PR).

PRs in this train, in order

• Web Configuration tab: all 28 Database Configuration columns and the Scoped Configuration table (Web Configuration tab: all 28 Database Configuration columns and the Scoped Configuration table #5105)
• Web System Events: show the desktop's parsed-row columns (Web System Events: show the desktop's parsed-row columns #5118)
• The stall probe ranks user-task waits first and counts the background ones (Slow reads and slow collector runs can't be diagnosed from the product: record each slow call's arguments, fix the stall probe's waits, keep store statement history, and export a diagnostics bundle #5097) (The stall probe ranks user-task waits first and counts the background ones (#5097) #5113)
• Web: analysis Recommendations tab on the server page (Add the WPF viewer's missing views to the web viewer, starting with FinOps #4843) (Web: analysis Recommendations tab on the server page (#4843) #5120)
