Force wrap-aware measure, serialize FineTune after measure content

feat: lazily load single-letter Pinyin candidates
- query the top 24 single-letter candidates from the database
- load the complete candidate list on the first page-down action
- apply the same behavior to Shuangpin and Quanpin
- resolve Shuangpin initials according to the active profile
- preserve candidate frequency adjustment and pinning
- disable deletion for single-letter candidates
- add regression tests for Shuangpin v-to-zh mapping and lazy expansion
Support tsf/sendinput/ctrl_v voice commit, route TSF inserts via worker
InsertText, handle WM_SYSKEYDOWN for Ctrl+Shift+Alt+digit candidate delete,
and skip watchdog when the IME profile is disabled.
Skip async AI/cloud refresh on paging and selection keys, early-exit when the
suggestion is already in the list, and dedupe series-cache inserts so repeated
cache hits no longer reset page_index or accumulate AI rows.
Refresh the menu toggle from general.floating_toolbar on show,
navigation, and config reload so it stays aligned with Settings.
