fix(mcp): point ckjia-shopping seed at production endpoint (#289)

The V85 seed shipped a dev/test placeholder (sse + http://localhost:8085/sse
+ "Bearer ${CKJIA_MCP_KEY}") that can never connect, so the 参考价 price-
comparison skill was unusable until an admin hand-edited the row.

Add V144 (h2 + mysql) to rewrite the seed to the real CKJIA SaaS endpoint:
streamable_http + https://m.ckjia.com/api/ai/mcp, no auth header, connect/read
timeouts raised to 60s. Conditional on the row still carrying the dev
placeholder URL, so an admin who already pointed it at a private deployment is
left untouched; idempotent and leaves `enabled` opt-in.
