fix: make forwardToStorage fully dynamic based on fileType

- Replace forceDocument boolean with fileType string in forwardToStorage
- Dynamically call matching sendPhoto, sendAudio, sendVideo, sendVoice, sendAnimation, sendSticker, or sendDocument Telegraf API method
- Correctly extract uploaded file details based on what Telegram returned
- Fixes IMAGE_PROCESS_FAILED 500 error when uploading ogg audio, video, sticker, or voice notes via HTTP
- Update upload.ts, bot.ts, and test suites to match the new dynamic signature
