[FIX] Reload app due to extension only on app update

[flavioislima]

This is a new approach from #1249.
It now checks everything only on the main process and has no issues with MM profile import.

AI Summary

This pull request includes several changes to the src/backend/main.ts and src/common/types/electron_store.ts files to handle app version updates and wallet connection state management. The most important changes include adding version checks, updating wallet connection state, and modifying the store structure to include new properties.

Version checks and updates:

• src/backend/main.ts: Added code to check and log app version changes, and update the stored app version in configStore.
• src/backend/main.ts: Modified the logic to reload the app if the wallet is not connected or if the app version has changed.

Wallet connection state management:

• src/backend/main.ts: Added event handlers for wallet connection, disconnection, chain changes, and account changes. These handlers update the configStore with the wallet state and notify the renderer process.

Store structure updates:

• src/common/types/electron_store.ts: Added appVersion property to the configStore structure.
• src/common/types/electron_store.ts: Added walletState property to the configStore structure to store wallet connection status, address, and provider.
