* zh-*: transition from "like" back to "fav"

This commit reverts the translation for the yellow-star "fav" button
back to "fav" in Chinese. Some ambuiguity between "like" and "fav" is
deliberately used in zh-TW/HK by using the existing phrase "最爱"
(favorite (adj.), lit. love-most) instead of "收藏" (favourite (v.),
"collect") in some instances.

Fixes #3511.

* zh-*: apply suggestions for PR #4557

* zh-cn: de-monetize ya account

In Chinese two separate characters, 账 and 帐, can be used to spell the
word for account (账/帐户). However, the one with a 贝 on the left is
evolved from the latter specifically for monetary purposes. Since
people usually can't figure out which one to use, it might be a good
idea to use the original not-so-money one.
