refactor(transcribe): extract t-mark + draw-cue policy into tested helpers (#327)
Review follow-up (Sara, fast-follow): the t no-active-region guard and the
draw-cue arm/disarm rule lived inline in the page with no direct coverage.
Extracted to pure resolveTrainingMark() (no-op when no region; recognition
enrolled flip) and canArmDraw()/shouldDisarmDraw(), each with unit tests
(10 cases total). The page now arms the draw cue only via canArmDraw and
disarms via shouldDisarmDraw, and routes t through resolveTrainingMark.

/**
* Policy for the "draw a new region" keyboard cue (the `n` shortcut) in the
* transcribe panel — issue #327.
*
* The cue is only valid while editing: `n` arms it in edit mode, and it must
* clear when a region is drawn or when the panel leaves edit mode. Pure so both
* rules are testable without mounting the page.
