### What problem does this PR solve?
Modifying a document’s parser config previously left behind obsolete
chunk images. If the dataset isn’t manually deleted, these images
accumulate and waste storage. This PR fixes the issue by automatically
removing associated images when the parser config changes.

### What problem does this PR solve?
Document list and filter supports metadata filtering.
**OR within the same field, AND across different fields**
Example 1 (multi-field AND):
```markdown
Doc1 metadata: { "a": "b", "as": ["a", "b", "c"] }
Doc2 metadata: { "a": "x", "as": ["d"] }
Query:
metadata = {
"a": ["b"],
"as": ["d"]
}
Result:
Doc1 matches a=b but not as=d → excluded
Doc2 matches as=d but not a=b → excluded
Final result: empty
```
Example 2 (same field OR):
```markdown
Doc1 metadata: { "as": ["a", "b", "c"] }
Doc2 metadata: { "as": ["d"] }
Query:
metadata = {
"as": ["a", "d"]
}
Result:
Doc1 matches as=a → included
Doc2 matches as=d → included
Final result: Doc1 + Doc2
```

This PR fixes incorrect naming for PostgreSQL usage by replacing all
instances of `postgresql` with the correct `postgres` in the `db_type`
field. This resolves potential configuration errors and ensures
consistency when specifying the database type.
Also fixed handling of None for `get_queue_length`

Traceback (most recent call last):

TypeError: int() argument must be a string, a bytes-like object or a real number, not 'NoneType'
```
This issue can happen very rare. When a `stream` is first created, the
`lag` value may be nil, which can cause this issue. However, once any
message is synced, the `lag` will become `0` afterwards.

When deleting knowledge base documents in RAGFlow, the current process
only removes the block texts in Elasticsearch and the original files in
MinIO, but it leaves behind many binary images and thumbnails generated
during chunking. This pull request improves the deletion process by
querying the block information in Elasticsearch to ensure a more
thorough and complete cleanup.
