Incorrect horizontal alignment of palm mute text

Issue type

Engraving bug (incorrect score rendering)

Description with steps to reproduce

1. Create a guitar staff with notes in it.
2. Apply palm mute (P.M.) to a note.
3. Observe the palm mute alignment.

Actual behavior: Palm mute is aligned to start from the left edge of the note. In the case of palm mutes, this is incorrect and often results in the text crossing over to the next note making distinguishing between muted and unmuted notes harder. (See attached example file)

Expected behavior: The palm mute text should be centered around the wanted note, making it a more sane default and reducing manual adjustments.

Workaround: manually adjust every single palm mute element separately (Style... > Text styles > Palm mute has no effect. https://github.com/musescore/MuseScore/issues/25585 )
