Subject: [PATCH] feat: add app setting page

Added AppSetting page:
- implemented 'language' drop down, with Eng and Chn language options
- implemented 'theme' drop down, with two staic options 'light', 'dark'
- drop down were wrote by custom ul li, implemented within react-hook-form
- added AppSetting page into routeConfig
- added entry from side nav bar
- added unit tests that passed after migrate to next
- changed theme hook to fit next js

Resolve CP-36
