Voice Phase V5: voice orb into the #25 SPA

[VforVitorio]

Sub of Epic #330. documents/audits/AUDIT_VOICE_STACK.md Phase V5 (size M). Fast-follow, tied to migration.

Scope: the voice orb into the migrated SPA.

• Move the React + ogl voice orb into the frontend-migration chore(security): clean up Critical Dependabot alerts (2 CVEs) #25 stack (it is lifted verbatim per the migration plan), wired to the hardened voice loop from V1/V2.

Deliverable: the voice orb lives in the #25 SPA, driving the fixed voice loop.

The voice surface was retired instead of audited/migrated (decision 2026-07-21): it came from a course requirement and added more weight than value. Removed in F1_Telemetry_Manager#184 and the parent #539/#540; it remains available in the legacy Streamlit app under src/telemetry/frontend/ and the legacy_version branch.
