FE: Topics: Remember user polling options

[Haarolean]

Polling options changed by the user should be persisted in localstorage per topic.

Settings to consider:

1. Polling mode (oldest/newest/etc)
2. Key/value serdes
3. Active filter(-s)
4. Search box text field

Local storage and the URL can conflict with each other we must determine which one has a priority and is the source of truth @Haarolean

I think, that in my case the URL will have the priority. That is what I discussed with @Haarolean
