S8 fix - help centre glossary classes leaked onto the Issue (hold) status pill

help.js injects its stylesheet on every page, and its glossary pills used bare
class selectors (.pill-draft ... .pill-hold). The creator's Issue (hold) status
radio also carries the class pill-hold, so the injected rule painted that radio
error-red at ALL times - selected or not. Reported by Nick ('why is the issues
(hold) button illuminated at all times'), 2026-08-20.

Pre-existing, not from this branch: help.js has had the bare selectors since
the login-portal commit, and the creator's pill-hold class predates the R2
branch. Every glossary rule is now scoped to .ui-help-pill.pill-*, which the
glossary markup already carries. Verified live: unselected, the hold pill's
computed style now matches its neighbours exactly; selected, it is still the
red fill; the glossary's own Hold pill keeps its tint. helptip_check gains the
pin (13 -> 14): no bare .pill-* selector in help.js, ever again.

Item: S8 (the help component's app-wide surface).
