fix(send-to/windows): reliable, windowless upload + options + context menu

Root cause of "token used but nothing uploaded": a SendTo shortcut to
powershell.exe did not forward the dropped files to the script ($args was
empty). Now a tiny launch.vbs receives the files reliably and starts the
uploader HIDDEN (no PowerShell window flash).

- send.ps1: writes send.log for diagnosis; notification is now optional.
- installer: interactive options (notification on/off; Send-to entry;
  "Drop on OpenCoperLock" / "Multi-Drop on OpenCoperLock" right-click
  entries). Registry writes use the .NET API to avoid the literal "*"
  all-files key being treated as a wildcard.
- new scripts/windows-context-menu-manager.{ps1,cmd}: enable/disable any
  right-click entry (classic verbs via LegacyDisable, shell extensions via
  the Blocked list); fully reversible, nothing deleted.
- docs + README updated; new download button for the menu manager.
