[CRE] Remove legacy DAG paths from workflows/wasm/host

[bolekk]

Strips the v1 legacy DAG machinery from the wasm host ahead of the DAG WASM removal (CRE-5836): ModuleV1/Run, linkLegacyDAG, IsLegacyDAG, GetWorkflowSpec, the legacy fetch/emit/log env imports and converters, the determinism random_get shim, the legacy poll_oneoff stub and fake clock, and the Fetch/MaxFetchRequests/Labeler/Determinism module config fields. IsLegacyDAG is also dropped from host.ModuleBase.

The sleep/oom test drivers are ported to v2 guests (rawsdk import) and driven via Execute, the two brotli/size tests are kept, and the 13 legacy guest test modules plus the dead test/requirements fixtures, mocks/module_v1 and its .mockery.yaml entry are deleted.
