Build workforce-api REST + MCP layers (Layer 3), full build in one pass

16 routes: Office (single key, full CRUD + employees sub-resource)
and Employee (single key, full CRUD + reports + customers
sub-resources). MCP layer built with the single-route pattern from
the start.

Only domain where customer role has zero access — verified against
ReferenceDataPermission.check(): read_only/product_manager/support
get reads, writes are admin-only, customer isn't in the allow-list
at all. All 9 MCP tool ACLs reflect this exactly.

Keycloak (local): workforce-api-audience + mcp-workforce-audience
client scopes, resource clients, broker/librechat attachments.
Deploy key and broker secret reused/mirrored, same pattern as every
domain since payments-api.
