Subject: [PATCH] fix(telegram): guard token.trim() against undefined to
 prevent startup crash

When account.token is undefined (e.g. missing botToken config),
calling .trim() directly throws "Cannot read properties of undefined".
Use nullish coalescing to fall back to empty string before trimming.

Closes #31944
