Filip Zubik 80a542252d Add config GUI, USB launcher, flash folder; fix bugs
- config-editor.hta: lightweight WYSIWYG HTA editor for config.json
  - Step on/off toggles with info tooltips
  - Editable software list (winget packages)
  - Settings: timezone, admin account, desktopInfo, PDF default
- Run.cmd: USB launcher with UAC auto-elevation and deployment menu
- flash/: minimal USB-ready subset (Deploy, scripts, config, GUI, launcher)
- config.json: add steps section for per-step enable/disable
- Deploy-Windows.ps1: read steps from config, CLI switches override
- 03-system-registry.ps1: add SearchOnTaskbarMode HKLM policy (Win11 search fix)
- 04-default-profile.ps1: fix systray - clear TrayNotify cache + proper Explorer restart
- 06-scheduled-tasks.ps1: fix Register-Task trigger array, ShowAllTrayIcons Win11 fix,
  PDF-DefaultApp runs as SYSTEM via HKCR (bypasses UserChoice Hash validation)
- 02-software.ps1: remove unreliable UserChoice ProgId write without Hash
