Fix/rejoin chat subscription

[the-only-queen-anna]

Context

This PR fixes some bugs and UI issues. If you have any suggestions for further fixes, feel free to comment (so we don't need to review and approve as many PRs).

Details

Changes include:

• fix for rejoin: I added the missing chat subcription after rejoin, cheating now works normally
• new send button: To make the hint section a bit nicer, I changed the send button to a send icon (also for sending chat messages). The hint section is also a bit smaller now, to avoid collisions with the android action bar. I could not fix any linebreaks here, because I could not recreate the issue (please test, if you own the mobile the issue occured on)
• fix for linebreaks on cards: I noticed that sometimes, the words are too long to fit in one line, so I changed the font size for longer words.
• some paddings adjusted.
• added error handling for invalid hints

Changes in the Codebase

• new AppSendButton
• some new responsive Dimensions (e.g., smallCardFontSize)
• see above
