Add Vault, Consul, eBPF connector plugins and thorough integration e2e tests

Backend:
- Add SecretsManager=9 type, Vault=550 and Consul=551 providers to IntegrationEnums
- Create VaultConnectorPlugin (GET /v1/sys/health), ConsulConnectorPlugin
  (GET /v1/status/leader), EbpfAgentConnectorPlugin (GET /api/v1/health)
- Register all 3 plugins in Program.cs and WebService.csproj
- Extend Concelier JobRegistrationExtensions with 20 additional advisory
  source connectors (ghsa, kev, epss, debian, ubuntu, alpine, suse, etc.)
- Add connector project references to Concelier WebService.csproj so
  Type.GetType() can resolve job classes at runtime
- Fix job kind names to match SourceDefinitions IDs (jpcert not jvn,
  oracle not vndr-oracle, etc.)

Infrastructure:
- Add Consul service to docker-compose.integrations.yml (127.1.2.8:8500)
- Add runtime-host nginx fixture to docker-compose.integration-fixtures.yml
  (127.1.1.9:80)

Frontend:
- Mirror SecretsManager/Vault/Consul enum additions in integration.models.ts
- Fix Secrets tab route type from RepoSource to SecretsManager
- Add SecretsManager to parseType() and TYPE_DISPLAY_NAMES

E2E tests (117/117 passing):
- vault-consul-secrets.e2e.spec.ts: compose health, probes, CRUD, UI
- runtime-hosts.e2e.spec.ts: fixture probe, CRUD, hosts tab
- advisory-sync.e2e.spec.ts: 21 sources sync accepted, catalog, management
- ui-onboarding-wizard.e2e.spec.ts: wizard steps for registry/scm/ci
- ui-integration-detail.e2e.spec.ts: detail tabs, health data
- ui-crud-operations.e2e.spec.ts: search, sort, delete
- helpers.ts: shared configs, API helpers, screenshot util
- Updated playwright.integrations.config.ts with reporter and CI retries
