Add VIP cards and the VIP panel (mt_vip)

Cards 38001 (7 days) and 38002 (30 days) extend all seven original premium
services of the account; the server side is metin2-server port_premium.h
(docs/FEATURE-VIP.md).

- mt_vip: /mt_vip 1 status, VIP button by the minimap, remaining time per
  service, chat line on card use.
- tools/server/vip-card: 40250 ships both cards with size 0 (two share a
  cell, neither moves); give them one cell, stacking, a log and no NPC sale,
  and name them on the server.
- locale_proto_patch: optional item shape table (size, flags, anti flags)
  so the client proto matches; data/zh_40250/item_shapes_server.tsv.
- Item mall (9010): 7 days 5,000,000, 30 days 18,000,000 gold.
