chore: remove 1-19 upgrade commands and navigation menu item feature flags (#19083)

## Summary
- Deletes the entire `1-19` upgrade version command directory (7 files,
~1500 lines) and removes all references from the upgrade module and
command runner.
- Removes `IS_NAVIGATION_MENU_ITEM_ENABLED` and
`IS_NAVIGATION_MENU_ITEM_EDITING_ENABLED` feature flags from the enum,
seed data, generated schema files, and test mocks. These flags had no
remaining feature-gated code — navigation menu items are now always
enabled.
