fix: create chunk with random uuid, no increase count num if index error

[Colstuwjx]

What problem does this PR solve?

Addresses issue by https://github.com/infiniflow/ragflow/issues/7150#issuecomment-2976432979 , aligned with dify behavior:

1. no increase chunk count / token count if index error;
2. set chunk id with a random uuid rather than using the hash string (one issue here is that ragflow is using uuid1 rather than uuid4, open for discussion)
