Part of #38790. Stacked on top of #44930.
Closes#43964.
Adds VPP and in-house datastore methods (`GetVPPAppConfiguration`,
`BulkGetVPPAppConfigurations`, `DeleteVPPAppConfiguration`,
`HasVPPAppConfigurationChanged`, plus in-house equivalents) keyed on the
merged `vpp_app_configurations` and `in_house_app_configurations`
tables. Wires them into `InsertVPPAppWithTeam`, `SaveInHouseAppUpdates`,
and the team / app removal paths.
Two follow-up bug fixes folded into this branch:
1. iPadOS in-house apps received no configuration: a single `.ipa`
upload creates two `in_house_apps` rows but config was only stored
against the iOS row's id, so iPadOS lookups returned NotFound. Now
writes to both sibling rows on insert and propagates updates / clears
via `installerIDsForInHouseAppSibling`.
2. Single-app PATCH with `"configuration": null` was inserting empty
bytes instead of deleting; aligned the iOS/iPadOS branch in
`InsertVPPAppWithTeam` with the batch path's `len > 0` upsert / `len ==
0` delete semantics.
