refactor(domains): merge token/tokens + scanner/scanners, drop empty app/domain/

- Move app/domains/tokens/deployer.py -> app/domains/token/deployer.py.
  Delete app/domains/tokens/ (was a single-file shadow of the token domain).
- Move app/domains/scanner/* into app/domains/scanners/core/. The 31
  detector modules in app/domains/scanners/ + the core service are now
  a single coherent domain.
- Update import paths in app/token_scanner.py and app/token_deployer.py.
- Delete empty app/domain/ (singular, was a leftover scaffold).
- Factory still loads 466 routes, mypy-gate clean.
