Adds a Preferences setting 'Virtualize long transcripts' (default ON, opt-out). When disabled, _currentMessageVirtualWindow returns a full non-virtualized window so the entire transcript renders at once (also short-circuits the virtual re-measure loop). Server-persisted (virtualize_transcript bool, default True), hot-applies via renderMessages on toggle. i18n in all 13 locales. Pairs with @rodboev's #4328 stream-end anchor scroll fix (cherry-picked into this branch) to fully resolve #4325.

The stream-end freeze/jump fix (#4328, semantic viewport anchoring) is covered by

test_issue500_message_list_virtualization.py. This file covers the new Preferences

toggle that lets a user disable virtualization entirely (opt-out, default ON).
