fix(worksheets): show ten-frames in smart mode when rule is 'always'

Fixed bug where ten-frames wouldn't show in smart mode even when
displayRules.tenFrames was set to 'always' (e.g., beginner preset).

Now sets show-ten-frames-for-all Typst variable to true when:
- Manual mode: config.showTenFramesForAll is true
- Smart mode: config.displayRules.tenFrames === 'always'

This ensures beginner mode shows ten-frames on all problems as intended.
