Fix stored procedure operation types with length-limited regex

- Add length limiters ({1,500} and {1,200}) to regex patterns in config-generator.ps1
- Prevents over-matching that was incorrectly changing InsertBook from mutation to query
- Fixes GetBooks, GetPublisher, and GetAuthorsHistoryByFirstName to be queries (read operations)
- Preserves InsertBook, CountBooks, DeleteLastInsertedBook, UpdateBookTitle as mutations (write operations)
- Regenerated both MsSql and DwSql configs with refined patterns
