Auto-reload transactions after AI makes changes

When the AI updates a category (or any tool result), the transactions
page now automatically reloads. ChatPanel triggers a refresh counter
in the usePageContext composable when the response includes a tool
result, and TransactionsView watches that counter to reload data.
