Load Saved Decks on Startup

[acezard]

Description:
As a player, I want my existing decks and their victory logs to load automatically when I open the app, so I can continue tracking without having to re-enter my data.

Acceptance Criteria:

• On app initialization, the app retrieves all saved decks and their associated data from local storage.
• If no saved data exists, the app starts with an empty state.
• The loaded decks display with the correct tabs and data intact.
• The app gracefully handles errors, such as corrupted or missing data in local storage.

Notes/Comments:

• This story ensures a seamless user experience across sessions.
• Consider adding error handling or a recovery mechanism if data retrieval fails.
