Key and scale are shown three times and the Key card truncates #736

Split out of #726.

What goes wrong

A track's key shows up as three separate fields that repeat each other. For a D major track the analysis strip shows "D maj" on the Key card, "Major" under it, and "Major" again on its own Scale card. Meanwhile the Key card is too narrow for a longer label such as "B harmonic minor".

Constraints

• Only the display is wrong. The stored key, scale and key_confidence values do not need to change, so no track needs re-analysis.
• Word order differs between languages, so a combined label has to come from a translated template, not from joining strings.
• The analysis cards share a grid with the stem-presence row below, which has to stay aligned.
