The F9 audit found that the Panel menu (Left/Right) was missing
the MC-style VFS link entries (FTP link..., Shell link...,
SFTP link...). The ConnectionDialog already supported all three
kinds but the user could only reach them via the catch-all
Cmd::Connection which defaulted to FTP.
Add three new Cmd variants (ConnectFtp, ConnectShell, ConnectSftp)
that each open the ConnectionDialog pre-set to the matching
ConnectionKind. Wire them into the Panel menu (Left/Right)
between 'External panelize' and 'Reload', separated by a
separator so the group reads as a VFS submenu.
Tests: 1393 pass, zero warnings.
