Feature: Split products catalog into Plain and Ready-Made

Replaces generic 'showOnProducts' boolean with separate catalog options:
- showAsPlain: for blank/unprinted items (/products/plain)
- showAsReadyMade: for pre-finished items (/products/ready-made)

Changes:
- Updated Product schema to replace showOnProducts with new fields
- Updated product creation and edit forms with new checkboxes
- Updated product listing pages to use showAsReadyMade filter
- Updated ProductDTO type to reflect new catalog flags

Products can now be precisely categorized by type with unique pricing for each.
