Fixes #5

Add functionality to replace full-width alphanumeric characters with half-width ones in specified fields.

* **src/lib/string.ts**: Add a utility function `replaceFullWidthWithHalfWidth` to replace full-width alphanumeric characters with half-width ones.
* **src/store/data.ts**: Import `replaceFullWidthWithHalfWidth` from `src/lib/string.ts`. Update the `transactions` computed property to use `replaceFullWidthWithHalfWidth` for the specified fields: receipt number and total number of nights stayed.
