Also added "PG" and "Checks" tables to flyctl machine status. The PG table is only displayed for "fly postgres" apps (and currently only displays the primary/replica Role). The Checks table is only displayed if the machine belongs to an app with healthchecks configured.

Note: We can currently view all checks for the app via flyctl checks list but this PR adds the machine specific checks to flyctl machine status for convenience.
