fix(setup): show a known manual step in the interactive dry run

The approval prompt now discloses a client's manual completion step,
but the interactive TTY dry run still printed only the planned file
changes, so `rea setup --dry-run --client grok_bot` hid the Grok Bot
connector step. The dry-run renderer now prints the planned result's
remediation the same way.
