TimeEntry: add POST /v1/timeentry/bulk for import parity

[CryptoJones]

Summary

Bulk create exists for 13 soft-deletable entities; TimeEntry has no POST /v1/timeentry/bulk. Importers and batch clients lack parity with Customer, Worker, Job, etc.

Proposed fix

Add bulk endpoint via _bulk-helpers.js factory (direct teCompId scoping) with same 500-entry cap, zod validation, transactional all-or-nothing semantics, and idempotency support.

Acceptance criteria

• POST /v1/timeentry/bulk implemented
• OpenAPI updated
• API + integration tests
• Postman collection regen documented
