feat(blueprints): backend foundation for fleet-wide compose templates (#860)

* feat(blueprints): add backend foundation for fleet-wide compose templates

Introduces the Blueprint Model: a docker-compose.yml plus a node selector
(labels or explicit IDs) that Sencho reconciles across the fleet. Backend
foundation only; the frontend tab and documentation follow.

Schema (DatabaseService):
- node_labels table for fleet-level orchestration tagging
- blueprints table with compose content, selector, drift_mode, classification
- blueprint_deployments table for per-node materialized state
- New idempotent migrate methods following the existing pattern

Services:
- BlueprintAnalyzer: pure compose-YAML classifier (stateless / stateful /
  unknown) with 17 covered cases including named volumes, bind mounts,
  external volumes, and tmpfs
- NodeLabelService: label CRUD plus selector matching helper (any/all/ids)
- BlueprintService: local + remote deploy/withdraw orchestration, marker
  file management, name-conflict guard, per-(blueprint,node) lock
- BlueprintReconciler: 60-second loop with three-mode drift policy
  (observe/suggest/enforce), state-aware guards, and Enforce-downgrade for
  volume-destroying drift

Routes (gated requirePaid + requireAdmin on mutations):
- /api/blueprints (CRUD + apply + withdraw + accept + preview + analyze)
- /api/node-labels (CRUD + listAll + listDistinct)

Notifications: four new categories registered in NotificationService for
deploy/failure/drift events.

Bootstrap: reconciler start/stop wired in startup and shutdown.

Tests: 45 new Vitest cases covering selector matching, classifier rules,
state-aware guards, drift-mode branching, and marker parsing. Full backend
suite (1625 tests) passes; tsc clean.

* fix(lint): replace bare Function type in blueprint reconciler tests

Replace 8 occurrences of `as unknown as { computeDecision: Function }`
with a properly typed `ReconcilerWithCompute` alias that mirrors the
real method signature. Export `ReconcileDecision` from
BlueprintReconciler so the test can reference it.

Resolves @typescript-eslint/no-unsafe-function-type errors that were
failing the Backend (Lint) CI step.

/**
* BlueprintReconciler decision-logic tests.
*
* The reconciler's `computeDecision` is the load-bearing pure logic — given
* a blueprint, an actual deployment table, and a desired node set, it must
* decide for each node whether to deploy, withdraw, drift-check, state-review,
* or evict-block. We test that decision in isolation by accessing the
* private method via a type-cast, mirroring the AutoHealService.shouldHeal
* pattern.
*
* Local deploy / remote HTTP / actual `docker compose` invocation are not
* exercised here — they're integration concerns covered by the manual
* lifecycle in the plan.
