fix: add Cmd+, shortcut to open Preferences on macOS

[jeanfbrito]

Description

Adds the standard macOS keyboard shortcut Cmd+, (Command+Comma) to open Preferences/Settings. This is a universal macOS convention — most native apps support it.

Changes

1. src/i18n/en.i18n.json: Added menus.preferences → "Preferences" translation key
2. src/ui/main/menuBar.ts: Inserted Preferences menu item in the macOS app menu (inside process.platform === 'darwin' block) with:
   • Label: Preferences
   • Accelerator: Command+,
   • Action: dispatches SIDE_BAR_SETTINGS_BUTTON_CLICKED (same as clicking Settings in the sidebar)

Menu order (macOS only)

Testing checklist

• Command+, is not used by any other menu item
• Only applies on macOS (process.platform === 'darwin' block)
• Click dispatches the same action as navigating to Settings
• Translation key added in en.i18n.json

Closes #3325

Walkthrough

This PR adds a native macOS Preferences menu item to the application menu. A new translation key menus.preferences is defined, and a corresponding menu entry is registered with the Command+, keyboard accelerator. Clicking the menu item or pressing the shortcut focuses the main window and dispatches an event to open the settings sidebar.

Check name	Status	Explanation	Resolution
Linked Issues check	❓ Inconclusive	The PR implements a macOS Preferences menu item with Cmd+, shortcut, which is a preliminary feature supporting the Click-to-Call objective. However, it addresses only the keyboard-shortcut infrastructure and not the telephony-specific objectives outlined in #3325.	Clarify whether this PR is intended as preparatory infrastructure for #3325 or verify that all telephony feature objectives from #3325 are fully implemented in the code changes.
