7TV emote support + Chat parser support for multiple emote providers

[GeleiaComPepino]

This PR adds support for 7TV emotes and integrates them into the Twitch chat.

Emotes are fetched directly from the 7TV API and rendered alongside native Twitch emotes.

---

What’s inside

• 7TV emote fetching via new backend endpoint
• Automatic loading of 7TV emotes per Twitch channel
• Chat parser support for multiple emote providers
• Proper emote source handling (twitch / 7tv)
• Twitch emotes take priority on name conflicts

---

How to test

• Run the app
• Open a Twitch channel with 7TV emotes enabled
• Send messages containing 7TV emotes
• Verify Twitch and 7TV emotes render correctly together

---

TODO

• Improve 7TV emote caching
• Add support for BTTV / FFZ emotes

Great work so far.

I see that zero-width emotes aren't working yet. They're the emotes that overlay the ones before them.

Looks like normal zero width emotes work great, but ones that are wider have a sizing issue.
