Tags, Categories and Payees on Payment/Deposit Investment Transactions don't calculate in Watchlists

Bug Description:

Watchlists created using tags do not accurately reflect the sum of transactions when those transactions originate from an investment account. While the individual tagged transactions from investment accounts are correctly displayed within the watchlist's detail view, the summary totals (e.g., "This Month," "Year to Date") shown on the watchlist overview or dashboard fail to include the amounts from these specific transactions.

Steps to Reproduce:

1. Navigate to an investment account.
2. Add a specific tag (e.g., "TagXYZ") to one or more transactions within that investment account.
3. Create a new watchlist (or view an existing one) that is filtered to show only transactions with "TagXYZ".
4. Observe the summary totals displayed for this watchlist (e.g., "This Month," "Year to Date" figures).
5. Click into the watchlist to view the list of individual transactions.
   

Actual Results:

The summary totals for the watchlist do not include the amounts from the tagged transactions originating in the investment account.

The detail view of the watchlist does correctly list the tagged transactions from the investment account.

Expected Results:

The summary totals ("This Month," "Year to Date," etc.) for the tag-based watchlist should accurately sum up all transactions matching the tag criteria, including those from investment accounts.

The totals should match the sum of the transactions listed in the watchlist's detail view.

Impact: This discrepancy makes tag-based watchlists unreliable for tracking totals that involve investment account activity.
