feat(errordialog): log the error code and record the silent stub

Adds the dialog to the silent-stubs list in docs/dev/TechnicalDebt.md, since it finishes without
showing anything. sceErrorDialogOpen now logs the error code and user id from the parameter
(offsets 4 and 8), like libSceMsgDialog logs its message, so an error a title would have shown
the player stays visible instead of disappearing.

 Throughout the project, every function at every stage either **does exactly what it's supposed to or throws an exception**. Everywhere... except:
 - [libSceSaveDataDialog.native](../../core/libs/prx/libSceSaveDataDialog.native/Export.cpp)
 - [libSceCommonDialog](../../core/libs/prx/libSceCommonDialog/Export.cpp)
+- [libSceErrorDialog](../../core/libs/prx/libSceErrorDialog/Export.cpp) - the error dialog runs the state machine but shows nothing; the error code passed to `sceErrorDialogOpen` is only logged
 - [libSceHmd](../../core/libs/prx/libSceHmd/Export.cpp) implements only the disconnected-headset path: initialization succeeds, device queries report `NotDetected`, and opening a device returns `DeviceDisconnected`. Headset support, tracking, rendering and additional HMD exports are not implemented; SDK-level ABI compatibility and in-game behaviour remain unverified.
 - [libSceNpCommerce](../../core/libs/prx/libSceNpCommerce/Export.cpp) - the PS Store icon show/hide calls do nothing
 - [sceVideoOutOpen](../../core/libs/prx/libSceVideoOut/src/Output.cpp) validates the priority and CPU affinity that the open param requests for the VideoOut service thread but does not apply them: the port's present and vblank threads are host threads, and guest priorities and affinities do not reach host scheduling
