Standardize on either "homeserver" or "server"

### Your use case

#### What would you like to do?
Standardize on either using the word "homeserver" or using the word "server" when describing the backend and then de-duplicate the strings. Using one standard word will be more clear to users and will result in less work for translators.

#### Why would you like to do it?
There are currently a fair number of strings which are nearly duplicates but one says server and one says homeserver. Here are some that I found:

Here are some bonus duplicates I found that aren't server/homeserver:
