Rename activation artifact to avoid invalid-name upload failure

[Copilot]

The activation job's artifact upload was failing across the entire smoke-test fleet with Create Artifact Container failed: The artifact name activation is not valid. GitHub's Actions artifact API rejects the bare single-word name activation, causing the upload step to fail before the agent job even starts.

Changes

• Renamed artifact constant: constants.ActivationArtifactName changed from "activation" to "aw-activation" in pkg/constants/job_constants.go. The activation job name itself (ActivationJobName) is untouched — only the physical artifact name changed.
• Recompiled generated workflows: all .lock.yml files under .github/workflows/ and pkg/cli/workflows/ regenerated so upload/download-artifact steps reference the new name.
• Updated tests: replaced hardcoded "activation" literals with constants.ActivationArtifactName in artifact-set resolution/filter tests and threat-detection step tests; regenerated wasm golden fixtures.

// Before
const ActivationArtifactName = "activation"

// After
const ActivationArtifactName = "aw-activation"

• Fixes [aw-failures] [P0] Artifact upload fails: "The artifact name activation is not valid" — smoke-test fleet outage #54116
