Subject: [PATCH] fix(payment): empty global min/max/daily displays correctly
 as empty
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

- Backend returns 0 for unset min/max/daily (not filled defaults)
- Frontend form: 0 displays as empty with placeholder "留空表示不限制"
- Save: empty → 0 → backend stores "" → returns 0 on next load
- Payment page: 0 fallback to sensible defaults (min=1, max=unlimited)
