Implement error handling and logging for sparkline and series methods

- Added rescue blocks to handle exceptions in the Accounts and AccountableSparklines controllers, logging errors and rendering error partials.
- Enhanced error handling in the Account::Chartable and Balance::ChartSeriesBuilder models, logging specific error messages for series generation failures.
- Updated the accounts view to include a timeout for Turbo frame loading.
- Added a test to ensure graceful handling of sparkline errors in the AccountsController.
