fix: Include recurring transactions in account balance calculations

[theperu]

🎯 Description

Recurring transaction occurrences were not contributing to account balances. When checkRecurringTransactions() runs at app startup, it generates real transaction rows (with recurring = 1) for each past-due occurrence. However, three queries in account_repository.dart explicitly filtered out any transaction with recurring = 1, meaning these auto-generated entries were completely invisible to balance calculations.

This fix removes that filter so that recurring transaction occurrences are correctly included in account totals, daily balance charts, and monthly balance charts.

Closes: N/A

📱 Changes

• Removed recurringFilter from selectAll() in AccountRepository — fixes account totals shown on the dashboard and accounts page
• Removed recurrentFilter from accountDailyBalance() — fixes the daily balance chart on the account detail page
• Removed recurrentFilter from accountMonthlyBalance() — fixes the monthly balance chart on the account detail page

🧪 Testing Instructions

Behaviour

1. Create a recurring transaction (e.g. monthly expense of €50) with a fromDate at least one recurrence period in the past
2. Restart the app so checkRecurringTransactions() runs and generates the occurrence(s)
3. Verify the account balance on the dashboard reflects the recurring transaction amount
4. Open the account detail page and verify the daily and monthly balance charts include the recurring transaction
