Can't input triplets or other tuplets with 6-key Braille entry

Issue type

Accessibility issue (e.g. for keyboard-only or screen reader users)

Description with steps to reproduce

In 4.7.4 triplets are now displayed correctly in Braille. But there does not seem to be a way to enter them using 6-key entry in the Braille panel.

STEPS:

1. With focus on an empty bar press Tab to move to the Braille panel.
2. Press N to input notes.
3. Press the following key combinations to enter a 4th octave mark followed by 3 crotchet C's. k fjkl fjkl fjkl.
4. Now press sd (dots 23) for the Braile triplet sign. The screen reader does announce "tuplet 3" but the crotchet rest remaining in the bar does not change to 3 quaver rests and the triplet sign does not display.
5. Now try to enter 3 triplet quaver C's fjk fjk fjk. Nothing is entered.

As MuseScore usually has the note length set before the triplet is used to break it into 3, the Braille input for the triplet will likely need to remain partial until all 4 signs have been entered and then display once the last triplet note enters. For combinations of a triplet with 2/3 1/3 it should resolve once 2 notes have been entered that add up to 3 of the smallest entered.

Reproduce the report in the Braille panel using 6-key entry and the key sequences given, then trace the Braille note-entry path for tuplets. Done means triplet and other tuplet signs are accepted, the entered notes are represented with the correct duration, and the tuplet becomes visible at the appropriate point described in the issue.
