fix(ui): let confirm-dialog buttons grow to fit wrapped labels (#6617)

* fix(ui): let confirm-dialog buttons grow to fit wrapped labels

The global `button { height:32px }` rule also applies to styledConfirm's
buttons. A label that wraps to two lines, such as "Delete chat and images",
"Launch anyway (CPU)" or a three-button dialog's alternate action, keeps
one line's height, so its second line renders below the button. On narrow
windows the dialog makes the buttons equal width, so this hits most
multi-word labels; it also happens on desktop, where the dialog box is
narrow too.

Give .styled-confirm-box .confirm-btn height:auto with min-height:32px.
Single-line buttons keep their current 32px.

Bumps the shared stylesheet/app cache token and the service worker cache
name, since a stylesheet changed.

* chore(static): leave admin.js's cache tag unchanged

* fix(cache): keep upstream's service worker cache name format

dev's editor tests require CACHE_NAME to match
odysseus-v<N>-pr40-editor-precache, so keep the version bump and use
that suffix.
