Bug 1 - Reveal mode not working (all browsers):
sessionSubstitutions stored "ademo demo" (full name) as key, but
buildRevealPairs looked up "ademo" and "demo" individually. No match,
no reveal pairs, reveal did nothing. Fixed by also storing individual
words from multi-word replacements so both "ademo demo" AND "ademo"
AND "demo" are in the map.
Bug 2 - Missing await on _handleDecryptedMeta (sync.js):
Two call sites returned the Promise instead of the resolved value.
Downstream code checking decResult.data got undefined. Added await.
Bug 3 - Profile selector broken by safeHTML (popup.js):
DOMParser.parseFromString wraps content in <html><body> which
mangles <option> elements when moved to a <select>. Replaced with
new Option() DOM API which creates proper option elements.
