* fix(vertex_ai): return a 400 naming the line for wrong-shape and non-UTF-8 batch rows

Keep main's error path for a directly raised provider error and only unwrap
one found behind a transport error. Add the parser column to invalid JSON
errors, and cover the real aiohttp chain in the _handle_error test

* fix(vertex_ai): report every row conversion error as a 400 naming its line

A message with no role, a non-string role, a bad temperature, or a litellm
BadRequestError raised while converting a row still returned a 500, and the
async upload lost the 400 for litellm's own exceptions. The stream now turns
any error from one row's conversion into a 400 naming that line.

_handle_error only unwraps an httpx.TransportError, which is what the aiohttp
transport raises around a failing request body, so other callers keep their
own status. A file that starts with a UTF-8 byte order mark now uploads, and
provider messages start with 'Batch input file line N' like the proxy check.

* fix(vertex_ai): reject null or missing batch bodies and unparseable rows with a 400 naming the line

A chat row whose body is missing or not an object now raises a 400 naming
its line instead of uploading a blank prompt, and a non-object body on
line 1 no longer crashes the GCS object name lookup. Rows too deeply nested
or too long to parse return a 400 from both the SDK and the proxy's own
batch file check. JSON error columns now count leading whitespace.

* fix(vertex_ai): keep batch rows on their file line through router and guardrail rewrites

The Router model rewrite and batch guardrails now keep blank lines and blank out dropped records, so a provider error naming a line still points into the caller's file. The rewrite strips a leading BOM per line, and a non-string body.model on line 1 is reported as a 400 naming the line

* test(integration): cover Vertex batch row line errors across routes, rewrites, SDK and worker chaos

* fix(router): keep blank lines only for Vertex batch uploads and leave guardrail rewrites compact

* test(integration): score the whole OpenAI upload after a guardrail drop and cover a mixed OpenAI and Vertex batch upload
