'--last' doesn't work for all st2 CLI endpoints

We recently introduced --last -1 #3735 param to show all CLI results and forced pagination to 50 per page for CLI output (some CLI previously reported ALL results by default).
However --last present only for some CLI endpoints.

Ideally to have all the CLI working in the same manner & make it consistent and predictable.

And while some CLIs are missing --last, for example currently st2 action list outputs ALL the results, while other CLIs limit output to only 50 results.

List of working CLI endpoints with --last:

• st2 execution list
• st2 key list
• st2 rule list
• st2 trace list
• st2 trigger-instance list
• st2 rule-enforcement list

Missing --last param

• st2 action list
• st2 action-alias list
• st2 apikey list
• st2 pack list
• st2 policy list
• st2 policy-type list
• st2 webhook list
• st2 timer list
• st2 runner list
• st2 sensor list
• st2 trigger list
• st2 role list
• st2 role-assignment list

Example CLI missing --last

$ st2 action list --last 1
usage: st2 [-h] [--version] [--url BASE_URL] [--auth-url AUTH_URL]
           [--api-url API_URL] [--stream-url STREAM_URL]
           [--api-version API_VERSION] [--cacert CACERT]
           [--config-file CONFIG_FILE] [--print-config] [--skip-config]
           [--debug]
           {run,action,action-alias,auth,login,whoami,apikey,execution,inquiry,key,pack,policy,policy-type,rule,webhook,timer,runner,sensor,trace,trigger,trigger-instance,rule-enforcement,role,role-assignment}
           ...
st2: error: unrecognized arguments: --last 1

Start by comparing the existing --last behavior in the listed working endpoints with the missing endpoints, using st2 action list --last 1 as the reproduction case. Review the CLI entry points for each missing list command and their help output. Done means all listed endpoints accept --last and use consistent result limits and pagination behavior.
