String Numbers not shown in Braille Panel

Issue type

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

Description with steps to reproduce

Currently in 4.7.4 a range of articulation, ornaments, bow markings, etc are shown in Braille. String numbers do not currently show.

STEPS:

1. Add a note to a score and from the fingering palette choose a string number.
2. Tab to the Braille panel and notice that the note has no extra sign with it.
   The Braille should show dots 146 (string sign) followed by the number (same as finger numbers) before the note.
   i.e. for violin:
   String 1 (E String) = 146, 1
   String 2 (A String) = 146, 12
   String 3 (D string) = 146, 123
   String 4 (G string) = 146, 2

Note that currently the speech is also incorrect on these as in the score it announces them as "finger 2", "finger 4", etc when they are actually string numbers. When adding them via the palette they do announce correctly in the pallette as "String 1", "String 2", etc. See #27954

• This report follows the guidelines for reporting bugs and issues
• I have verified that this issue has not been logged before, by searching the issue tracker for similar issues
• I have attached all requested files and information to this report
• I have attempted to identify the root problem as concisely as possible, and have used minimal reproducible examples where possible

Start by reproducing the issue from the fingering palette and checking the Braille panel, using the listed violin string-number mappings as the expected output. Verify that string numbers produce the 146 string sign followed by the correct number and that the score announces them as string numbers rather than finger numbers.
