[Fix] Five webview visual tests fail on every pull request (#2209)

* test(webview): refresh stale toolkit baselines missed by #2163

Regenerate the five baselines that #2163 left on the mocked toolkit
rendering: history-rename-editor in all four themes and
opencode-go-temperature. Captured by the pinned
mcr.microsoft.com/playwright:v1.62.1-noble container via the Visual
Regression workflow on this branch.

The real toolkit places the search field's icon inline inside the field
and renders the custom-temperature checkbox inline with its label
(480x359 -> 480x340), matching the intended appearance from #2163.

Fixes #2206

* ci(webview): drop pull_request path filter from Visual Regression

The Protect Main ruleset should require the webview-visual check. GitHub
keeps path-filtered workflows in a pending state on pull requests that
do not match the filter, so a required check would block those PRs from
merging. Remove the pull_request paths filter so webview-visual,
theme-fixtures, and extension-host-visual report on every pull request,
like code-qa and e2e already do. The merge_group event ignores path
filters, so merge-queue runs are unchanged.
