413f01c06 (#15403 by @Sean-Kenneth-Doherty) Improve NSIS configuration path errors so missing installer icons and images include the related config key and path.

2857c01c6 (#15422 by @koki-develop) Fix NSIS stock plugins (NSISdl.dll, StartMenu.dll, System.dll, nsDialogs.dll) being embedded in the final installer as unsigned despite the signing step succeeding. The signed local copies under <output>/Plugins/x86-unicode/ were not on makensis’ plugin search path, so makensis fell back to the unsigned DLLs from the NSIS toolset directory. The fix adds !addplugindir for the signed plugin directory before any plugin command is parsed in the script.
