chore(db): consolidate 14 migrations into single 20260526000000_init

合并 W3 之前所有增量 migration 为单文件 init，便于 fresh deploy。
旧 migration 已在 dev 环境跑过；prod 首次部署直接走 init。

apps/pac-service/prisma/migrations/20260513223154_remove_platform_field_mapping/migration.sql

--- Remove deprecated Platform.field_mapping column.
--- AssemblerEngine + per-host assembler.yaml(`apps/pac-service/data/<host>/assemblers/*.yaml`)
--- 已完全替代该字段;保留它只会让 v1 / v2 模型混淆。
-ALTER TABLE "platforms" DROP COLUMN IF EXISTS "field_mapping";

apps/pac-service/prisma/migrations/20260514090545_plan_reason_split/migration.sql

--- Plan 模型重构:patient-级 plan + scenario-级 plan_reasons 子表

apps/pac-service/prisma/migrations/20260514163449_platform_to_host_and_patient_profile/migration.sql

--- 大重命名:platform → host(表 + 列)+ Patient 重构 + PatientProfile 副表 + fact_type 清理
-
--- 1) 重命名 platforms 表
-ALTER TABLE "platforms" RENAME TO "hosts";
-
--- 2) 重命名 platform_id 列 → host_id(子表 12 个)
-ALTER TABLE "patients"               RENAME COLUMN "platform_id" TO "host_id";

-
--- 5) fact_type 清理:删 6 个衍生类 + 重命名 charge_order_record → order_record + appointment_plan → appointment_record
--- 由于 dev mock 数据,直接删 fact 行而非 transform
-DELETE FROM "patient_facts"
-  WHERE "type" IN ('diagnosis_record', 'treatment_record', 'treatment_plan',

-UPDATE "patient_facts" SET "type" = 'appointment_record' WHERE "type" = 'appointment_plan';
-
--- 6) action / subjectType 重命名
-UPDATE "patient_transactions" SET "action"       = 'order_submitted' WHERE "action"       = 'charge_order_submitted';
-UPDATE "patient_transactions" SET "subject_type" = 'order'           WHERE "subject_type" = 'charge_order';
