Improve font setting interaction on the mobile

[gdy106]

Is there an existing issue for this?

• I have searched the existing issues

Can the issue be reproduced with the default theme (daylight/midnight)?

• I was able to reproduce the issue with the default theme

Could the issue be due to extensions?

• I've ruled out the possibility that the extension is causing the problem.

Describe the problem

之前反馈过思源移动端交互难用的问题，当时建议过参考Taio，D大回复是思源交互主要以notion为参考，但是notion的大部分操作都是通过键盘那半块区域完成的，而不是占用手机本来就小的上半部分编辑区域。

思源的字体外观菜单会占手机上半屏，键盘占下半屏，我连我有没有选错块都看不到，而且操作完也没有反馈，选完以后有没有成功生效也看不到。

Expected result

把字体外观界面合并进键盘区域，并针对移动端的小屏放大字色选项的大小（参照notion）
