feat: use polling in docker development to enable hot reload

documentation:
https://vite.dev/config/server-options#server-watch
-> https://github.com/paulmillr/chokidar/tree/3.6.0#performance
->
```
usePolling (default: false). Whether to use fs.watchFile (backed by
polling), or fs.watch. If polling leads to high CPU utilization,
consider setting this to false. It is typically necessary to set this to
true to successfully watch files over a network, and it may be necessary
to successfully watch files in other non-standard situations. Setting to
true explicitly on MacOS overrides the useFsEvents default. You may also
set the CHOKIDAR_USEPOLLING env variable to true (1) or false (0) in
order to override this option.
