[Tablet] ExerciseEditDialog has multiple fixed label widths

[9thLevelSoftware]

Problem

ExerciseEditDialog.kt contains multiple fixed widths that create rigid layouts.

Platforms Affected

• ✅ Android tablets
• ✅ iPads (iOS)

Affected Areas

Element	Size	Line
Label width	width(60.dp)	~91
Label width	width(100.dp)	~127
Label width	width(120.dp)	~148
Input field	width(120.dp)	~229

Current Behavior

Creates rigid layouts that don't adapt. Labels ("Sets:", "Set 1:") are cramped, input fields shrink unnecessarily. Spacing is inefficient on wide tablets.

Expected Behavior

Dialog content should use responsive layouts that adapt to available space.

Suggested Fix

Use Modifier.fillMaxWidth() with weight(1f) or flexible padding to create responsive layouts.
