Telegram's file API returns application/octet-stream instead of the
actual image type. Added inferMimeType() that detects the real type
from the URL extension (jpg→image/jpeg, png→image/png, etc.) when
the server response Content-Type is generic.

checkHealth() now returns 'ok' | 'rate_limited' | 'auth_error' | 'unreachable'
instead of boolean, so /status can display the specific issue with color-coded
indicators instead of just "Nicht erreichbar" for all failures.

- Add centralized friendlyError() helper mapping technical errors to
clear German messages (rate limit, auth, network, timeout, etc.)
- Improve /status to handle rate limits gracefully
- Improve album upload: abort early on rate limit/auth, show partial
results with failure reason
- Better file-type rejection: show the rejected extension, suggest
sending as photo instead
- Friendlier Telegram download errors (file too big, getFile failures)
- Add global bot.catch() handler for unhandled Grammy errors
- Truncate long unknown errors to 150 chars

Show German messages with retry time for 429 and helpful guidance for
401 instead of raw API error JSON.

Payload CMS REST API requires document data (alt, tenant, etc.) as a
JSON string in a _payload form field, not as individual form fields.
