[Fix] Resolve SSH Directory Issue

[RichardAnderson]

This pull request introduces a minor change to the exec method in app/Helpers/SSH.php to improve command execution context. The update ensures that commands run as a specific user are executed from the user's home directory.

• Command Execution Context:
  • Modified the command template to include a cd /home/{$this->asUser} statement before executing commands as the specified user, ensuring the working directory is set appropriately.

Pull request overview

This PR aims to fix failures when executing SSH commands as an isolated site user by ensuring the command runs from that user’s home directory (instead of inheriting the SSH login user’s working directory).

Changes:

• Prepends a cd /home/<asUser> before running sudo -u <asUser> bash in SSH::exec() to adjust the working directory for commands executed as another user.
