Fix migration require paths after reorganization

- Updated all core migrations to use ../../src/ instead of ../src/
- Updated legacy migrations with the same path fix
- This fixes MODULE_NOT_FOUND errors during deployment

The error occurred because migrations were moved one level deeper
into core/ and legacy/ subdirectories without updating the relative
paths to the source files.
