The four sidecar prepare-time helpers (PipelockProxy, Egress, GitGate,
Supervise) had docker-flavored subclasses that existed only as
instantiation shims for ABCs that already had no abstract methods.
PipelockProxy.prepare() reached for class-level CA path constants
that were only defined on the docker subclass — so smolmachines had
to import DockerPipelockProxy to render pipelock yaml, reaching
across the backend boundary for what's actually a platform-neutral
operation.
This moves the universal in-container CA paths
(PIPELOCK_CA_CERT_IN_CONTAINER / PIPELOCK_CA_KEY_IN_CONTAINER) to
claude_bottle/pipelock.py, drops the class-attr indirection on the
ABC, and deletes the four empty docker subclasses. Both backends
now instantiate the ABCs directly; the docker-side modules keep
the docker-flavored helpers (image pin, container naming, host CA
mint) and re-export the moved pipelock constants for compat.
