CoopCycle must host a S/FTP server for transporter synchronisation

[r0xsh]

Several transporters have requested the provision of an S/FTP server for handling SCONTR files. To accommodate this, we need to implement an S/FTP server and ensure the transporter feature supports multiple filesystems.

Requirements:

1. S/FTP Server Setup: Host an S/FTP server to facilitate the transfer of SCONTR files.

2. Multiple Filesystem Support: Update the transporter feature to integrate with multiple filesystems, allowing for flexible storage options.
