Unblocks the documented core workflow and closes the AI-service exposure, without changing existing behaviour. Job/JobApplication split (additive; see ADR-002): - New Job entity (the opportunity) with owner-scoped query filter; nullable JobApplication.JobId FK. Nothing reads Job yet. - Migration AddJobEntityAndProspectStages, hand-edited to drop reconciler-owned tables the scaffolder re-emitted; verified against the real dev DB. Pipeline: 10 internal stages across three concerns kept separate — PipelineStage (workflow) / PipelineGroup (UI: NotApplied/Active/Closed) / PipelineCategory (analytics). Adds Saved/Interested/Preparing/Withdrawn; keeps Waiting and Ghosted. Kanban shows 3 grouped columns; cards keep a stage chip and full transitions; drag applies only safe transitions (never infers Ghosted/Withdrawn). DateApplied nullable + SavedAt. Cleared when leaving Applied so analytics stay accurate; the discarded date is preserved as an AppliedDateCleared JobEvent. AI service lockdown: no host port; private ai_internal network (backend is the only other member); X-Ai-Service-Token required on all non-/health endpoints; AI_SERVICE_TOKEN mandatory via compose. Verified backend-only against the live stack. Also carries two pre-existing working-tree files (views/ProfilePage.tsx, views/CareerWorkspacePage.tsx) so the tree is clean for the branch integration. Tests: +40 backend (247 total), +5 sidecar (16), +15 frontend. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
