What this PR does and why

A deployment from the swiss plan (helm backend) disappeared from the list right after Uninstall, even though its pods kept terminating for a while. modelsphere/swiss#31 now keeps that row listed with phase: uninstalling until the resources are gone. It also reports an LLMService with a deletionTimestamp the same way. This PR shows that state in the UI and turns off the actions that would now get a 409.

Loading

• A single isUninstalling() helper (web/src/modules/swiss/lib/phase.ts) checks the row phase, helm status/helmStatus, planStatus.phase and llmservice.phase. It takes precedence over failed, applying, not installed and no pods.
• Inferences list and detail: the Uninstalling / 卸载中 state is shown, and Uninstall, Upgrade/Edit, SLO edit and rollback are disabled with a reason.
• Embedded swiss UI (list, detail, upgrade, revisions): shows an uninstalling badge and disables Uninstall, Upgrade and Roll back.
• Polling is unchanged, so the row leaves the list once swiss stops returning it. No Go or API changes are needed here.

Which issue(s) this PR fixes

Closes #94

How it was tested

• Unit tests cover the state helpers: row phase, planStatus, llmservice, precedence, and helm uninstalling. Component tests render the list and detail of both front-ends with an uninstalling deployment and a serving one, and assert the label and the disabled or enabled actions.
• npm run typecheck, npm test (47 files, 418 tests), npm run build and npm run build:swiss pass, as do gofmt -l . (empty), go vet ./... and go test ./....
• Not clicked through in a browser against a live swissd.

Checks

• go test ./... and gofmt -l . is empty
• npm run typecheck && npm test && npm run build in web/
• Docs updated (deploy guide, en-US and zh-CN)
• No internal hostnames, IPs, registries or credentials

Release note

Uninstalled deployments now stay listed as "Uninstalling" until their pods are gone; edit and uninstall are disabled meanwhile.

[huskcass]

No blockers.

Verdict: good to merge alongside modelsphere/swiss#31. The single phase helper, the disabled actions and the component tests cover both front-ends, and nothing changes against an older swissd.
