- Modified the `buildPrefixKey` function to include an optional `manualValues` parameter, allowing manual input values to be incorporated into the prefix key.
- Adjusted the sequence allocation process in `allocateCode` to extract manual values before building the prefix key, ensuring accurate prefix generation.
- Removed the fallback to the "BULK1" value in manual configurations, preventing unintended overwrites and ensuring user input is prioritized.
- Enhanced the `joinPartsWithSeparators` function to prevent consecutive separators when handling empty parts, improving the output format.
- Added a new migration script to clean up existing "BULK1" values from the database, ensuring data integrity.
These changes address several issues related to manual input handling and improve the overall functionality of the numbering rule service.
