**Related issue:** Related to #47839
Follow-up to #47949 (same root cause, same issue). That PR fixed the
OR-dominance drop out in the software *title summary* queries; this
applies the same fix to the four per-host queries behind a host's
*software details* page.
A host with more than one queued install or uninstall for the same
installer, VPP app, or in-house app could disappear from its software
details page: the old self anti-join's `(priority < OR created_at >)`
predicate let two rows eliminate each other, so neither survived. This
rewrites those four queries (`hostSoftwareInstalls`,
`hostSoftwareUninstalls`, `hostVPPInstalls`, `hostInHouseInstalls`) to
rank with `ROW_NUMBER()` and keep one row per item. No performance
change — these are per-host queries.
