[eas-cli] Add --ssh to workflow:run

[gwdp]

Why

Lets you enable SSH when starting a run, so you can connect to it afterwards with eas workflow:ssh:

eas workflow:run --ssh

How

Adds --ssh and --ssh-idle-timeout to workflow:run, feeding a single SSH input on both run-creation mutations that marks the run's VM jobs as SSH-enabled.

• --ssh-idle-timeout without --ssh is rejected.
• The server owns the timeout default and clamp.

Test Plan

Unit tests cover input resolution, including the timeout-without---ssh rejection. CI passes.
