[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. The flags feed a single SSH input on both run-creation mutations, which 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.
