Improve SSH config file safety in dockerimg/ssh_theater.go

- Add SafeWriteFile method to the FileSystem interface that:
  - Writes data to a temporary file first
  - Syncs to disk to ensure data is written
  - Creates a backup of the original file (if it exists)
  - Safely renames the temporary file to the target

- Update all file modification operations to use SafeWriteFile:
  - addContainerToSSHConfig
  - removeContainerFromSSHConfig
  - addContainerToKnownHosts
  - removeContainerFromKnownHosts
  - CheckForIncludeWithFS

This change reduces the risk of corruption if the process is interrupted
while modifying configuration files.
