Fix capitalisation in room settings panel

### Steps to reproduce

1. Open room settings

### Outcome

#### What did you expect
Consistent capitalisation in room details

#### What happened instead?
Room Photo, Room Name, Direct Chat are capitalised US style, while everything else is GB style (only first letter is capitalised). Given that we use en_GB as default, these should be updated to be Room photo, Room name and Direct chat

Search the iOS project for the room settings labels “Room Photo,” “Room Name,” and “Direct Chat,” then inspect the surrounding localization entries. Update them to “Room photo,” “Room name,” and “Direct chat,” and verify that the room details panel consistently uses the requested capitalization.
