fix(openclaw): allow upgrading kernel to latest patch

OpenClaw Chinese edition has advanced to 2026.5.12-zh.2 while the panel still recommended 2026.5.12-zh.1 and treated same-base zh patch versions as equivalent.

This updates the recommended Chinese kernel target and makes the version comparison detect suffix-level upgrades such as zh.1 -> zh.2 when both sides expose suffixes. It also adds explicit latest-upstream upgrade actions on the Services and About version cards so users can upgrade to the latest detected upstream version without going through the manual version picker.

## Changes
- update OpenClaw Chinese recommended target to 2026.5.12-zh.2
- detect same-base suffixed patch upgrades in version info
- add Services page "upgrade to latest" action and confirmation copy
- add About page latest-upstream action

## Verification
- npm run build
- cargo check
