Convert batched ingest content as text, not as a locator

`_ingest_batched` asserts its payload is inline content and then passed it to
`HaikuRAG.convert`, which disambiguates a str by parsing it: anything whose
scheme reads as http or https is fetched over the network instead of stored.
`urlparse` strips leading whitespace, so a passage beginning with a newline
and a URL qualifies.

187 passages across MTRAG's cloud and fiqa corpora start that way, which
crashed the pooled build. No clapnq passage does, so mtrag_clapnq and every
other existing dataset is unaffected.

Now converts through the configured converter's text path, which is what
create_document already does.

 ### Fixed
 
+- Batched evaluation ingest converts inline content as text instead of letting `HaikuRAG.convert` disambiguate it, so a passage beginning with a URL is stored rather than fetched over HTTP. 187 MTRAG cloud and fiqa passages start with one; no clapnq passage does, so no existing dataset's numbers change.
 - `mtrag_federated` builds vacuum each collection after ingest and assert the chunks FTS index covers every row. Without the vacuum the index stays at zero rows, and full-text search returns near-arbitrary rows while still returning results.
