[ADD] put_in_pack_stock: Created custom put in pack module

- **Custom Put in Pack Button:**
  - Added a button in stock move list to package the full line quantity.
  - Removed existing move lines before creating a new packaged one.

- **Detailed Operations Wizard Update:**
  - Updated the detailed operations wizard from the hamburger button.
  - Added fields for package quantity, package size, and package type.
  - Integrated a "Generate Packages" button inside the wizard.

- **Lot Number Handling:**
  - Implemented logic for both **quantity-tracked** and **lot-tracked** products.
  - Assigned packages correctly for each lot while distributing quantities..

- **Inventory View Enhancements:**
  - Added a **Group By Packaging** filter in Inventory Locations view.
  - Allows users to view stock grouped by packaging type.
