Support more third-party account connections

Problem

I wish that there's should be more connections in Fluxer, particularly those who cared about connecting their accounts to Fluxer.

Proposed solution

Ideally, Fluxer should copy Discord's existing connections one to one, but not all partnering entities would be interested to collaborate, as some may dodge AGPL projects like no tommorrow. As of me writting this draft, Discord had added 23 supported connections, but people wanted them to support more connections (shown in new additions section). Additionally, since there will be many proposed connections planned to be added, sort them in their respective categories like Developer, Entertainment, Gaming, Music and Social Media. Developer:

• ☐ Github

Entertainment:

• ☐ Crunchyroll
• ☐ Twitch

Finance/Retail:

• ☐ Ebay
• ☐ Paypal

Gaming:

• ☐ Battle.net
• ☐ Bungie.net
• ☐ Epic Games
• ☐ League of Legends
• ☐ Playstation Network
• ☐ Roblox
• ☐ Riot Games
• ☐ Steam
• ☐ Xbox

Note that it depends whether to support both Riot Games and League of Legends or only support Riot Games. That would be up to discussion.

Music:

• ☐ Amazon Music
• ☐ Spotify

Social Media:

• ☑ Bluesky
• ☐ Facebook
• ☐ Reddit
• ☐ Tiktok
• ☐ Twitter/X
• ☐ Youtube

Miscellaneous:

• ☑ Domain

New Additions:

• ☐ Bandcamp (Music)
• ☐ Cash App (Finance/Retail)
• ☐ Chess.com (Gaming)
• ☐ Codeburg (Developer)
• ☐ Deezer (Music)
• ☐ en.pronouns.page (Miscellaneous)
• ☐ Kick (Entertainment)
• ☐ Gitlab (Developer)
• ☐ GOG.com (Gaming)
• ☐ guns.lol (Miscellaneous)
• ☐ Instagram (Social Media)
• ☐ itch.io (Gaming)
• ☐ Lichess (Gaming)
• ☐ Mastodon (Social Media) (mentioned in #1162)
• ☐ Monkeytype (Gaming)
• ☐ Newgrounds (Music)
• ☐ Ninja Kiwi (creators of BTD fanchise) (Gaming)
• ☐ Odysee (Entertainment/Social Media)
• ☐ osu! (Gaming)
• ☐ Soundcloud (Music)
• ☐ speedrun.com (Gaming)
• ☐ Threads (Social Media)

Notes (optional)

I am aware that some connections are proposed before I write this draft. Therefore, I will give to those who suggested a connection eariler than me. I know that there is a lot of connections, but adding existing discord connections should have a higher priority.
