fix: update Gofile website token generation

[chubbygrannychaser]

Summary

• Load the current Gofile website token secret from Gofile's WT script instead of using a stale hardcoded value.
• Cache the loaded secret and await website-token generation for guest token creation and content requests.
• Treat not-premium/denied-access responses as guest-token auth failures so they can refresh once.

Tests

• npm run typecheck:node
• npx eslint src/main/services/hosters/gofile.ts
• pre-push hook: eslint . --fix (warnings only), typecheck:node, typecheck:web
