Captcha check accidently removed

[Lumi-Script]

Previously it hit the captcha check endpoint which would return 'false' if no captcha is required for generation,. The UI would display instructions to generate a song on suno.ai if captcha is required, refreshing the token.

This logic was incorrectly removed when I refactored some files - need to identify the captcha check endpoint and add it back, so a captcha check is run prior to generation.

[Lumi-Script]

const captchaCheck = await fetch("/api/c/check", {
"method": "POST",
"headers": headers,
"body": JSON.stringify({"ctype": "generation"})
});

if (!captchaCheck.ok) {
// Logic to deal with non-200 response, likely a cookie issue - throw error back
}

if (await captchaCheck.json()).required) {
// Throw error stating to generate a song on suno
}

Something like this in services/SunoGenApi.ts should do the trick. Will implement once tested, for now if you get an error saying to 'refresh the page' it's likely a captcha is required and you'll need to generate a song on suno.com.

I don't plan on adding captcha solving (which can be done just via clicking in certain spots on the page) as it requires browser rendering.

[Lumi-Script]

fetch("https://studio-api-prod.suno.com/api/c/check", {
"headers": headers,
"body": "{"ctype":"generation"}",
"method": "POST"
});

The captured command, returns:
{
"required": false,
"captcha_version": 1
}
