refactor: Get Thunderstore package API response from backend

[GeckoEidechse]

Previously Thunderstore package index was done in frontend. Should be moved to backend instead as backend is reponsible for such tasks while frontend should just be used to store and display information.

Closes #164
Closes #120 cause filtering no longer happens in frontend but instead in backend.

@Alystrasz any idea how to get rid of the undefined warning?

Trying to use an if-guard just gives another error :(

CI failing cause Ubuntu Azure repos are down (still) and cause of TypeScript warning mentioned in #168 (comment) that I will need assistance with to solve.

You need to initialize your mods variable, and type it as an array of Thunderstore mods.
Then, instead of checking if mods is undefined (which isn't a good practice btw), you can check if the list is empty:

let mods: ThunderstoreMod[] = []; await invoke<ThunderstoreMod[]>("query_thunderstore_packages_api") .then((message) => { mods = message; }) .catch((error) => { console.error(error); return; }); if (mods.length === 0) { return; }

Thanks for the clarification, fixed in 394f561. Empty check isn't needed then anyway cause it's implicitly handled due it being an (empty) array. ^^

Assuming CI passes now, this PR should be done and ready for review ^^

Ok, now it should be fixed ^^"
