Apply fails when tty mode enabled on podman target

Describe the Bug

Enabling the tty mode for Podman exec commands results in bolt apply and apply blocks failing with:

> bolt apply -e 'notify { "Hello": }' -t podman://nest-stage1-haswell-workstation --log-level=debug

Expected Behavior

Apply mode should not be affected by a setting that should only affect run_command.

Steps to Reproduce

Steps to reproduce the behavior:

1. Define inventory with:

   config:
     podman:
       tty: true
   

2. Apply code to a container target.

   bolt apply -e 'notify { "Hello": }' -t podman://container-name
   

Environment

• Bolt 4.0.0 (gem)
• Podman 5.1.1
• Gentoo

Additional Context

I want to use TTY mode to signal to commands that they can output in color.

Start by reproducing the provided bolt apply command with Podman tty enabled, then trace how the Podman transport applies tty settings during apply and run_command operations. Done means apply and apply blocks succeed with tty enabled while run_command retains the intended TTY behavior.
