Game bring-up: ProsperoStore (PPSA99000): catalog loads with #8346, #9834 and #11134

[p3n1cillin]

Status: on main the store stops at startup on sceAppInstUtilInitialize not implemented. With #8346 it starts, but its catalog never loads: "The catalog is on its way". With #9834 and #11134 as well, the catalog loads and the signed update check works.

Setup (the runs reported in #11134)

• Title: ProsperoStore (PPSA99000, homebrew catalog), converted with the catalog runner.
• Machine: Windows 11 Pro (26300), Ryzen 5 7600X, WinLibs GCC 15.2.0, Release. Run from a cleared /data/prosperostore, 60 s each, on a separate desktop, muted.

The stops on main

terminate called after throwing an instance of 'std::runtime_error'
  what():  sceAppInstUtilInitialize not implemented

With #8346, the HTTPS catalog request fails because libSceHttp has no request transport, so it stays on "The catalog is on its way".

With #8346, #9834 and #11134

• The catalog loads: "New in the catalog 12".
• The store's signed update check offers 01.000.106.
