Subject: [PATCH] fix: fetchT() now handles self-signed HTTPS certs

- Node.js native fetch() (undici) cannot use rejectUnauthorized:false
- Added _httpsFetch() using raw https module for internal .sami endpoints
- Fixes quality profile fetch for Sonarr/Radarr (was returning "fetch failed")
- Also fixed corrupted proces..._KEY -> process.env.PYLON_KEY in pylon

Coderbot fix #1
