🎨 Palette: Localize Notification Channel Label and Description

[manupawickramasinghe]

💡 What: Replaced raw technical strings used for the Notification Channel's name and description with localized string resources (notification_channel_name and notification_channel_desc).
🎯 Why: When users go to Android System Settings > App Info > Notifications, they were previously seeing internal identifiers like REMOTE_CAM. This change presents a polished, human-readable name like "RemoteCam Service" and a descriptive explanation, which improves transparency and the overall professional feel of the app.
📸 Before/After:
Before: App settings showed channel name REMOTE_CAM and description RemoteCam run.
After: App settings show channel name RemoteCam Service and description Background service running RemoteCam.
♿ Accessibility: Improves clarity for screen reader users navigating the system notification settings.
