Add timeouts and delays to backup sends

Browse source 
Add rate-limit friendly delays and context timeouts when sending backups via Telegram. Iterate admin IDs with index to sleep 1s between sends; add 30s context.WithTimeout for each SendDocument call and defer file.Close() for opened files; insert a 500ms pause between sending DB and config files. These changes improve resource cleanup and reduce chance of Telegram rate-limit/timeout failures.
