0.4.0-preview6: square shapes everywhere, EUC motor temp tiers, placeholder fix

UI:
 - Every Button / OutlinedButton / TextButton / OutlinedTextField /
   AssistChip / AlertDialog now passes shape = RoundedCornerShape(0.dp).
   Material3 Buttons defaulted to a pill shape that ignored
   MaterialTheme.shapes, so Service Mode still looked rounded after the
   theme override. Now every component is hard-edged.
 - Commands tab: each command button is a fixed 80.dp tall so the row
   layout stays uniform with 2-line descriptions; outer LazyColumn
   gets contentPadding(bottom = 24.dp) so the last category clears the
   dialog edge.
 - Inspect grid: contentPadding(bottom = 16.dp) so the last byte row
   doesn't kiss the dialog frame.

Dashboard:
 - Temp / battery / voltage stat cards now show the placeholder ("-")
   instead of a deceptive "0%" / "0.0V" / "32 °F" when the parser
   hasn't decoded a real value yet (the 32 °F bug was the Fahrenheit
   conversion of an internal 0 °C reading — looked like a real freezer
   reading, was actually "no data").
 - Placeholder changed from em-dash to ASCII hyphen.
 - Temp color tiers raised to EUC-realistic thresholds:
     <70 °C  green
     70-90  yellow
     90-105 orange
     >105   red
   (always evaluated on stored °C so the rule holds for °C and °F users).
