Skip column truncation when stdout is piped (non-TTY)

When stdout is not a terminal (e.g. piped to grep, awk, cat), output
full column values without truncation. This follows the standard CLI
pattern used by docker ps, kubectl get, etc.

- Table column truncation in PrintTableNoPad now checks IsTerminal
- truncateURL also skips truncation in non-TTY mode
- TTY behavior (truncate to terminal width) is unchanged
