Clarify trade condition title

Prices are defined on Supply Line inside Sale Trade Condition.

Drop prices from Subscription Condition.
Instead, link the Subscription Condition to a Sale Trade Condition.

Apply the Sale Trade Condition on the created Open Sale Order.

Stop duplicating properties from the Subscription Condition to the created Subscription Request.

Payment is managed by the 'payment' category, and not the language.

This allows to remove all '==zh' conditions.
Instead, use custom Sale Trade Condition.
