Daniil Sivak c93ec0a1f3 Fix: reject empty/space-only content in update_chunk API (#14082) ...

Closes #6541

### What problem does this PR solve?

Add content validation to `update_chunk` (SDK and non-SDK) to reject
empty or whitespace-only content before it reaches the embedding model.

**Before:** Calling `update_chunk` with space-only content (like `" "`,
`""`, `"\n"`) bypassed validation and was sent directly to the embedding
model, which returned an error. This was the same bug previously fixed
for `add_chunk` in #6390, but `update_chunk` was missed.

**After:** Empty/whitespace-only content is caught by validation and
returns an error: `` `content` is required ``
