feat(deploy): production deployment setup and fixes

- Debian-based api image (bookworm-slim), docker/debian mirrors, prisma
  binaryTargets for openssl 3.0
- nginx: admin SPA under /admin, TLS via acme.sh (ZeroSSL) + auto-renewal
  cron, http->https redirect
- prisma: add origin_goods.delisted migration, sync missing schema
  (good_image/tag_font_color/good_tags), fix users.createdAt Timestamptz
- api: CORS wildcard reflection, helmet CORP cross-origin, price
  backfill in persistProductDetail, categoryIcon ancestor fallback,
  mediaByColor per-color gallery in public goods detail
- admin: /admin base path (vite + router)
- import-data.mjs: udt_name casting, serial sequence advance fix

-# Client Utilities

-Pure functions for formatting, validation, transformation, and parsing.
-
-## Quick Reference
-
-| Category     | Examples                                      |
-| ------------ | --------------------------------------------- |
-| Formatters   | `formatCurrency`, `formatDate`, `formatBytes` |
-| Validators   | `isValidEmail`, `isValidUrl`, `isValidPhone`  |
-| Transformers | `slugify`, `truncate`, `capitalize`           |
-| Parsers      | `parseQuery`, `parseJSON`, `parseDate`        |

-## Rules
-
-**Pure functions:**
-
-- Same input → same output
-- No side effects
-- No external state mutation
-- No API calls, no refs, no reactive
-
-**When NOT to use utils:**
-
-- Stateful logic → use composables
-- Vue-specific → use composables
-- Component logic → keep in component
-- API calls → use queries
-
-## Structure
-
-```ts
-// utils/formatters.ts
-export function formatCurrency(amount: number, currency = 'USD'): string {
-  return new Intl.NumberFormat('en-US', {
-    style: 'currency',
-    currency,
-  }).format(amount)
-}
-
-export function formatRelativeTime(date: Date): string {
-  const rtf = new Intl.RelativeTimeFormat('en', { numeric: 'auto' })
-  const diff = date.getTime() - Date.now()
-  const days = Math.floor(diff / (1000 * 60 * 60 * 24))
-  return rtf.format(days, 'day')
-}
-```
-
-**Naming:** Descriptive verbs (`formatCurrency`, `validateEmail`, `parseQuery`)
-**Organization:** Group by category (`formatters.ts`, `validators.ts`)
-**Exports:** Named exports only
-
-## Examples by Category
-
-**Formatters:**
-
-```ts
-// utils/formatters.ts
-export function formatBytes(bytes: number): string { ... }
-export function formatPhone(phone: string): string { ... }
-```
-
-**Validators:**
-
-```ts
-// utils/validators.ts
-export function isValidEmail(email: string): boolean {
-  return /^[^\s@]+@[^\s@][^\s.@]*\.[^\s@]+$/.test(email)
-}
-
-export function isValidUrl(url: string): boolean {
-  try { new URL(url); return true }
-  catch { return false }
-}
-```
-
-**Transformers:**
-
-```ts
-// utils/transformers.ts
-export function slugify(text: string): string {
-  return text.toLowerCase()
-    .replace(/[^\w\s-]/g, '')
-    .replace(/\s+/g, '-')
-}
-
-export function truncate(text: string, length: number): string {
-  return text.length > length ? `${text.slice(0, length)}...` : text
-}
-```
-
-**Parsers:**
-
-```ts
-// utils/parsers.ts
-export function parseQuery(search: string): Record<string, string> {
-  return Object.fromEntries(new URLSearchParams(search))
-}
-
-export function parseJSON<T>(json: string, fallback: T): T {
-  try { return JSON.parse(json) }
-  catch { return fallback }
-}
-```
-
-## Common Mistakes
-
-**Side effects (not pure):**
-
-```ts
-// ❌ Wrong - mutates external state
-let count = 0
-export function increment() {
-  count++
-  return count
-}
-
-// ✅ Correct - pure
-export function add(a: number, b: number): number {
-  return a + b
-}
-```
-
-**Using utils for stateful logic:**
-
-```ts
-// ❌ Wrong - should be composable
-export function useCounter() { ... }
-
-// ✅ Correct - pure transformation
-export function formatCount(count: number): string { ... }
-```
-
-## Organization
-
-**Flat for small projects:**
-
-```
-utils/
-├── formatters.ts
-├── validators.ts
-└── transformers.ts
-```
-
-**Nested for large projects:**
-
-```
-utils/
-├── formatters/
-│   ├── date.ts
-│   ├── currency.ts
-│   └── index.ts
-└── validators/
-    ├── email.ts
-    └── index.ts
