* refactor(ui): align approval page with redesigned approval card
Follow up #124767 by carrying severity accents and identity chips onto the standalone approval page.
Remove the unused execApproval.labels severity, plugin, and agent keys.
* refactor(ui): keep approval-page helpers in repo idiom
Reverts drive-by rewrites from the build pass: restore the exhaustive
decisionLabel switch (the ternary lost the never check), the early-return
appliedDecisionMatches, explicit gatewayCode comparisons, and align the
severity mapping shape with the sibling exec-approval-card.ts.
* test(ui): type approval severity fixtures
* test(scripts): wait for a parseable descendant pid in Bun smoke cleanup
The readiness gate only required the descendant pid file to exist, but
existsSync can observe it between open() and write(); a loaded runner
then reads an empty file and the integer assertion flakes (seen on PR
#124816 CI run 31971191374). Readiness now requires parseable content.
