feat(phase-2): workstream 1 — HashiCorp Vault credential storage

Vault is optional — server falls back to bcrypt (Phase 1 behaviour)
when VAULT_ADDR is not set. Full coexistence: existing bcrypt credentials
continue to work until rotated.

Changes:
- src/vault/VaultClient.ts — wraps node-vault KV v2; writeSecret,
  readSecret, verifySecret (constant-time), deleteSecret
- src/db/migrations/005_add_vault_path.sql — vault_path column on credentials
- CredentialRepository — createWithVaultPath, updateVaultPath methods
- CredentialService — routes generate/rotate through Vault when configured;
  bcrypt path unchanged
- OAuth2Service — verifies via Vault when vaultPath set, bcrypt otherwise
- src/app.ts — createVaultClientFromEnv() wired into service layer
- ICredentialRow — vaultPath field added
- docs/devops/environment-variables.md — VAULT_ADDR, VAULT_TOKEN, VAULT_MOUNT
- docs/devops/vault-setup.md — dev quickstart, production config, migration guide
- tests: 33/33 unit tests pass (VaultClient + CredentialService Vault path)
- node-vault + @types/node-vault installed
