Description of problem:

• When using hammer on Satellite 6.18.0 (presumably this affects any version using hammer), using 0 for the --per-page flag's value returns "Error: Infinity"

  [root@satellite ~]# hammer host list --per-page 0
  -----|-----------------
  NAME | OPERATING SYSTEM
  -----|-----------------
  Error: Infinity 

• Using a value of 1 or greater returns output from hammer host list as expected (using --fields "name,operating system" for output brevity)

  [root@satellite ~]# hammer host list --fields "name,operating system" --per-page 1
  --------------------------------------|-----------------
  NAME                                  | OPERATING SYSTEM
  --------------------------------------|-----------------
  example-host1.fqdn-example.com        | RHEL 9.6        
  --------------------------------------|-----------------
  Page 1 of 4 (use --page and --per-page for navigation).

  How reproducible:

Consistently

Is this issue a regression from an earlier version:

Unknown

Expected behavior:
Hammer should warn that 0 is an invalid value for --per-page
