chore(crm): 验证 Generated Column 自动生成 — 无需修改 plugin.toml

验证所有实体的 unique/filterable/sortable 标记已正确配置，
build_create_table_sql 将自动为以下字段生成 Generated Column：
- customer: code(unique), customer_type/industry/region/level/status(filterable)
- communication: type(filterable), occurred_at(sortable)
- customer_relationship: relationship_type(filterable)

同步更新 Cargo.lock（moka 依赖引入）
