anti a27e3f5e0f fix(tests+mutator): unbreak the docker-shadow test env + let mutator delete from active
Two related fixes that came out of running the W5 tests locally:

1. tests/__init__.py — empty file, makes 'tests/' a package so pytest
   stops inserting it into sys.path.  Without it, 'tests/docker/'
   (the docker-image test category) shadowed the installed docker SDK
   on every engine-touching test in the repo:

     module 'docker' has no attribute 'DockerClient'

   Pytest's default --import-mode=prepend was the culprit; making
   tests/ a package is the cheapest fix and doesn't change
   --import-mode for the whole tree.

2. delete_topology_decky / delete_topology_edge / delete_lan grow an
   'enforce_pending: bool = True' kwarg.  Default preserves the HTTP
   CRUD guard (api_decky_crud / api_edge_crud / api_lan_crud get the
   409 for free).  apply_remove_decky / apply_detach_decky /
   apply_remove_lan now pass enforce_pending=False — the mutator
   queue is the live-editing surface and has its own active-topology
   gating; the repo's pending-only guard was for design-time CRUD
   that mustn't bypass it.  Without this, apply_remove_decky was
   silently broken on active topologies pre-W5; W5's new test
   surfaced it on first run.

10/10 new W5 tests pass; 58/58 across mutator + topology suites.
