Add Call Log Filtering

[jelectric]

Overview

This PR introduces real-time filtering to the main call log and optimizes the Settings activity layout for better space utilization and visual balance.

Changes

Features: Call Log Filtering

• Filter Chips: Added a horizontal scroll of Material Filter Chips at the top of the main screen.
• Multi-select Logic: Users can now filter the log by Incoming, Blocked, Missed, and Outgoing calls (supports selecting multiple filters at once).
• Expanded History: Updated the call log query to include Outgoing calls, which were previously omitted.
• Localization: Added "Outgoing call" translations for Spanish, Italian, Portuguese, Japanese, and Russian.

UI/UX Improvements

• Settings Layout: Removed redundant top padding and balanced the spacing between the "Export/Import" buttons and the title bar/scrolling list.
• Theme Stability: Updated the app theme to use Theme.MaterialComponents.DayNight to ensure Material components (like Chips) inflate correctly and menus remain visible in light mode.

Build

• Robustness: Updated app/build.gradle.kts to safely handle environments where local.properties or specific release signing keys are missing, preventing build failures for new contributors.

Verification

• Verified real-time filtering on a Samsung Galaxy S20 FE.
• Confirmed the settings menu layout is symmetrical and buttons are easily accessible.
• Build verified with ./gradlew assembleDebug.
