flatpak: missing emoji fonts in launcher

[draeath]

This is a very low priority issue. On discord, someone confirmed that the Steam version of the launcher is not affected by this.

I noticed today that server names with emojis in them draw the emoji as a generic box character, despite the org.freedesktop.Platform runtime including files/share/fonts/noto-emoji/NotoColorEmoji.ttf which does include the characters I found missing.

Here's what it looks like on my system (opensuse tumbleweed):

Here's my console rendering it correctly while dumping my launcher settings.db favorites table. Note I am using the same font for emojis on this system, though of course installed under /usr rather than the copy in the flatpak runtime:

Finally, here's the font being included in the runtime:

draeath@ginnungagap:~> file $(flatpak info --user --show-location org.freedesktop.Platform)/files/share/fonts/noto-emoji/NotoColorEmoji.ttf
/home/draeath/.local/share/flatpak/runtime/org.freedesktop.Platform/x86_64/24.08/69f5ca3180618e77eb1264af2b67048fc1c6a2884ee403c76b24b0e15bfc16c9/files/share/fonts/noto-emoji/NotoColorEmoji.ttf: TrueType Font data, 13 tables, 1st "CBDT", 15 names, Microsoft, language 0x409, Copyright 2022 Google Inc.Noto Color EmojiRegularVersion 2.047;GOOG;noto-emoji:20240827:6c211821

I did notice that #84 references the noto sans font, presumably referencing this one: https://github.com/space-wizards/SS14.Launcher/tree/v0.31.0/SS14.Launcher/Assets/Fonts/noto_sans

I wonder if the noto emoji font needs to be bundled in as an asset and somehow made available to whatever it is that's responsible for font rendering in the launcher?

I can't self-replicate this on a machine running Mint.
