Add VersionMismatch error variant and check_version() helper to erp-core.
All 13 mutable entities now enforce version checking on update/delete:
- erp-auth: user, role, organization, department, position
- erp-config: dictionary, dictionary_item, menu, setting, numbering_rule
- erp-workflow: process_definition, process_instance, task
- erp-message: message, message_subscription
Update DTOs to expose version in responses and require version in update
requests. HTTP 409 Conflict returned on version mismatch.
- Add POST /config/menus (create single menu)
- Add PUT /config/menus/{id} (update single menu)
- Add DELETE /config/menus/{id} (soft delete single menu)
- Frontend MenuConfig was calling individual CRUD routes that didn't exist,
causing 404 errors on all create/update/delete operations
- Fix frontend to correctly handle nested tree response from backend
- CORS: replace permissive() with configurable whitelist (default.toml)
- Auth store: synchronously restore state at creation to eliminate
flash-of-login-page on refresh
- MainLayout: menu highlight now tracks current route via useLocation
- Add extractErrorMessage() utility to reduce repeated error parsing
- Fix all clippy warnings across 4 crates (erp-auth, erp-config,
erp-workflow, erp-message): remove unnecessary casts, use div_ceil,
collapse nested ifs, reduce function arguments with DTOs
- C-1: Add tenant_id to settings unique index to prevent cross-tenant conflicts
- C-2: Move pg_advisory_xact_lock inside the transaction for correct concurrency
(previously lock was released before the numbering transaction started)
- H-5: Add CORS middleware (permissive for dev, TODO: restrict in production)
