fix(kiloclaw): clarify "Upgrade & Redeploy" copy (#966)

## Summary
- Changes "Upgrade to the latest KiloClaw version" to "Upgrade to the
latest **supported** KiloClaw version" in the Redeploy dialog's "Upgrade
to latest" radio option.
- Clarifies that the upgrade targets the latest *supported* platform
image, not necessarily the absolute latest OpenClaw release.
