Fix text color visibility in dark theme dialogs

Add explicit white70 color to dark theme text styles to ensure text is visible against dark dialog backgrounds. This matches the pattern used in light theme where black87 is explicitly set.

-# Icon Regeneration Guide
-
-This document describes how to regenerate app icons from the source icon files.
-
-## Source Icons
-
-- **Primary source**: `res/icon.png` (2048x2048 PNG) - Used for iOS and Android
-- **SVG source**: `flutter/assets/icon.svg` - Vector format, can be used to generate any resolution
-- **macOS source**: `res/mac-icon.png` - Specific macOS variant
-
-## Prerequisites
-
-Install required tools:
-```bash
-sudo apt-get install librsvg2-bin imagemagick
-```
-
-## Regenerating iOS Icons
-
-### Method 1: Using ImageMagick (Manual)
-
-```bash
-#!/bin/bash
-SOURCE_ICON="res/icon.png"
-OUTPUT_DIR="flutter/ios/Runner/Assets.xcassets/AppIcon.appiconset"
-
-# Function to generate icon with alpha removal for iOS
-generate_icon() {
-    local size=$1
-    local filename=$2
-    convert "$SOURCE_ICON" -resize ${size}x${size} -background white -alpha remove -alpha off "$OUTPUT_DIR/$filename"
-}
-
-# iPhone icons
-generate_icon 40 "Icon-App-20x20@2x.png"
-generate_icon 60 "Icon-App-20x20@3x.png"
-generate_icon 29 "Icon-App-29x29@1x.png"
-generate_icon 58 "Icon-App-29x29@2x.png"
-generate_icon 87 "Icon-App-29x29@3x.png"
-generate_icon 80 "Icon-App-40x40@2x.png"
-generate_icon 120 "Icon-App-40x40@3x.png"
-generate_icon 120 "Icon-App-60x60@2x.png"
-generate_icon 180 "Icon-App-60x60@3x.png"
-
-# iPad icons
-generate_icon 20 "Icon-App-20x20@1x.png"
-generate_icon 40 "Icon-App-40x40@1x.png"
-generate_icon 76 "Icon-App-76x76@1x.png"
-generate_icon 152 "Icon-App-76x76@2x.png"
-generate_icon 167 "Icon-App-83.5x83.5@2x.png"
-
-# App Store icon
-generate_icon 1024 "Icon-App-1024x1024@1x.png"
-```
-
-### Method 2: Using flutter_launcher_icons (Automated)
-
-```bash
-cd flutter
-flutter pub run flutter_launcher_icons
-```
-
-This uses the configuration in `flutter/pubspec.yaml`:
-```yaml
-flutter_icons:
-  image_path: "../res/icon.png"
-  remove_alpha_ios: true
-  ios: true
-  android: true
-```
-
-## Regenerating Android Icons
-
-```bash
-SOURCE_ICON="res/icon.png"
-BASE_DIR="flutter/android/app/src/main/res"
-
-convert "$SOURCE_ICON" -resize 48x48 "$BASE_DIR/mipmap-mdpi/ic_launcher.png"
-convert "$SOURCE_ICON" -resize 72x72 "$BASE_DIR/mipmap-hdpi/ic_launcher.png"
-convert "$SOURCE_ICON" -resize 96x96 "$BASE_DIR/mipmap-xhdpi/ic_launcher.png"
-convert "$SOURCE_ICON" -resize 144x144 "$BASE_DIR/mipmap-xxhdpi/ic_launcher.png"
-convert "$SOURCE_ICON" -resize 192x192 "$BASE_DIR/mipmap-xxxhdpi/ic_launcher.png"
-```
-
-Or use `flutter_launcher_icons` as shown above.
-
-## Updating Source Icon from SVG
-
-If you need to regenerate the source PNG from the SVG at a different resolution:
-
-```bash
-# Generate 2048x2048 PNG from SVG
-rsvg-convert -w 2048 -h 2048 flutter/assets/icon.svg -o res/icon.png
-
-# Or for even higher resolution (4096x4096)
-rsvg-convert -w 4096 -h 4096 flutter/assets/icon.svg -o res/icon.png
-```
-
-## iOS Icon Requirements
-
-- All iOS icons must have alpha channel removed (opaque)
-- White background is applied to maintain appearance
-- Icons are automatically rounded by iOS system
-- Retina displays require @2x and @3x variants
-
-## Icon Sizes
-
-### iOS
-- 20pt (20x20, 40x40, 60x60)
-- 29pt (29x29, 58x58, 87x87)
-- 40pt (40x40, 80x80, 120x120)
-- 60pt (120x120, 180x180)
-- 76pt (76x76, 152x152) - iPad
-- 83.5pt (167x167) - iPad Pro
-- 1024x1024 - App Store
-
-### Android
-- mdpi: 48x48
-- hdpi: 72x72
-- xhdpi: 96x96
-- xxhdpi: 144x144
-- xxxhdpi: 192x192
-
-## Quality Tips
-
-1. Always start from the highest resolution source available (SVG preferred)
-2. Use at least 2048x2048 PNG as intermediate source
-3. Let ImageMagick/flutter_launcher_icons handle downscaling
-4. Never upscale low-resolution images - regenerate from vector source
-5. Test on actual devices with Retina displays to verify quality
