Allow users to exclude specific accounts from the transaction feed and financial reports (budgets, spending summaries, trends, etc.) without fully removing or hiding the account from the app.

This would be useful for users who track accounts on behalf of family members or other people, where those transactions shouldn’t count toward their own spending or reporting. It would also help users who want to keep an account visible for balance tracking but not have its transactions pollute their overall financial picture.

The feature could work similarly to the existing “Hide Account” toggle but with more granularity – for example, a per-account setting like “Exclude from reports and transaction list” that keeps the account accessible but filters it out of aggregated views.
