refactor(P6): standardize route variable naming to router

All route files (admin.py, store.py) now export `router` instead of
`admin_router`/`store_router`. Consumer code (definition.py, __init__.py)
imports as `router as admin_router` where distinction is needed.
ModuleDefinition fields remain admin_router/store_router.

64 files changed across all modules. Architecture rules, docs, and
migration plan updated. Added noqa:API001 support to validator for
pre-existing raw dict endpoints now visible with standardized router name.
All 1114 tests pass.
