refactor(swap): integrate isExecutingPrice state for improved button …

…handling

- Added `isExecutingPrice` to the swap context to manage the execution status during price calculations.
- Updated the `Balance` component to disable the "Select Max" button when a price execution is in progress, enhancing user experience and preventing unintended actions during loading states.
