telegram: switch to HaskellNet for IMAP, fix message delivery bugs

- Replace openssl s_client with HaskellNet/HaskellNet-SSL for proper
  IMAP client support (better protocol handling, no manual parsing)
- Add HaskellNet deps to Haskell.nix with doJailbreak for version bounds
- Fix lost messages: sendMessageReturningId now throws on API errors
  instead of returning Nothing (which was incorrectly treated as success)
- Auto-retry markdown parse errors as plain text
- Hardcode benChatId for reliable email check loop startup
