fix: per-user Today, native paste and drop on a local machine

- Today's spend in the status bar and the Claude Code statusline is the
  caller's own (`GET /api/pricing/cost?mine=1`, scope.ownSessionWhere), not
  every user's sum for an admin or analyst.
- A screenshot pasted into a local claude pane is sent as Claude Code's own
  image-paste key: Alt+V on Windows (Ctrl+V did nothing there), ^V elsewhere,
  and only when the machine can read its clipboard (wl-paste/xclip + a
  display on Linux), else it is uploaded (GET /api/run/native-paste {key}).
- A file manager's files pasted or dropped on a local browser go in by their
  own paths, read from the OS clipboard or the file manager's selection
  (server/lib/file-manager.js, POST /api/run/clipboard-files and
  /selected-files): no upload, no size limit. A copied image file is pasted
  by path, text that comes with a picture of it (spreadsheet cells) is
  pasted as text, Windows paths go in as `C:/…` mentions.
- Tab titles for Snapshot, Artifacts, Files and Administration.
- An npm tool AgentHub installed under ~/.local is updated there, not by its
  own updater into npm's global prefix.
