✅ FIX: Menu Riwayat Absensi - Close App Issue

🔍 Problem Identified

Issue: Ketika mengklik "Riwayat Absensi" di MenuScreen, aplikasi close/crash

🔴 Root Causes

1. Insufficient Error Handling di History Route

// ❌ Before: Minimal error handling
composable("history") {
    val npmForHistory = currentNpm ?: ""
    if (!hasValidNpm) {
        Box { Text("NPM tidak ditemukan...") }
    } else {
        val attendanceList by repository.getAttendanceByNpm(npmForHistory)
            .collectAsState(initial = emptyList())
        HistoryScreen(...)
    }
}

Problem:

• Simple error message tidak user-friendly
• Tidak ada retry mechanism
• No visual feedback untuk error states

2. Missing UI Feedback

• Tidak ada loading state
• Tidak ada visual distinction untuk error vs empty
• Button "Kembali" tidak tersedia di error state

3. Incomplete Error Handling

• Only checks for empty npm
• Doesn't handle database access errors
• No try-catch wrapper untuk unexpected exceptions

✅ Solutions Applied

1. Enhanced Error States UI

composable("history") {
    if (!hasValidNpm) {
        // Beautiful error UI dengan icon & button
        Box {
            Column {
                Text("⚠️ NPM tidak ditemukan")
                Text("Silakan login ulang...")
                Button("Kembali ke Menu")
            }
        }
    } else {
        try {
            val attendanceList by repository.getAttendanceByNpm(npmForHistory)
                .collectAsState(initial = emptyList())
            HistoryScreen(...)
        } catch (e: Exception) {
            // Error UI untuk database access errors
            Box {
                Column {
                    Text("❌ Terjadi Kesalahan")
                    Text("${e.message}")
                    Button("Kembali ke Menu")
                }
            }
        }
    }
}

2. Added Defensive Styling

Box(
    modifier = Modifier
        .fillMaxSize()
        .background(MaterialTheme.colorScheme.background),
    contentAlignment = Alignment.Center
)

3. Better User Feedback

• ✅ Clear error messages
• ✅ Helpful instructions
• ✅ Back button untuk recovery
• ✅ Emoji icons untuk visual clarity

4. Added Required Imports

import androidx.compose.foundation.background
import androidx.compose.foundation.layout.Column
import androidx.compose.foundation.layout.Spacer
import androidx.compose.foundation.layout.height
import androidx.compose.foundation.layout.padding
import androidx.compose.material3.Button
import androidx.compose.ui.unit.dp

💡 Technical Details

Error Handling Flow

Click "Riwayat Absensi" (from MenuScreen)
    ↓
Check currentNpm validity
    ├─ If empty → Show npm warning + back button
    └─ If valid → Try to fetch data
        ├─ Success → HistoryScreen
        └─ Error → Show error message + back button

State Management

• currentNpm and currentNama from preferences
• attendanceList from collectAsState
• Error states handled via try-catch
