fix: honor parser params and image VLM system_prompt in Go ingestion (#17334)

## Summary Fix the Go ingestion pipeline so that several parser setup switches and the image VLM prompt are actually honored end-to-end (previously the DSL fields existed but the Go code never read them). - **DOCX** (`docx_parser.go`, `docx_postprocess.go`): read `remove_toc` and `remove_header_footer`; apply to both JSON and markdown output paths (outline-based TOC removal with a text-heuristic fallback, plus header/footer section filtering). - **HTML** (`html_parser.go`, `html_postprocess.go`, `text_toc.go`): read `remove_header_footer` (pre-parse strip of `<header>`/`<footer>` and ARIA `banner`/`contentinfo`) and `remove_toc` (post-parse `remove_contents_table` heuristic). - **Markdown** (`markdown_parser.go`): read `flatten_media_to_text` and force media blocks to text when enabled. - **Image VLM** (`media_dispatch.go`): read `system_prompt` instead of `prompt` so the user-configured image VLM prompt is no longer silently dropped (`prompt` remains the video family key). All flags are wired through `ConfigureFromSetup`, which the dispatch layer already invokes for every family, so the behavior is live rather than dead code. ## Test plan - New unit tests: `docx_postprocess_test.go`, `html_parser_test.go`, `text_toc_test.go`, `markdown_parser_test.go`, `media_dispatch_test.go`. - `bash build.sh --test ./internal/parser/parser/... ./internal/ingestion/component/...` ## Notes - The `File` component is excluded from this migration scope. - Relates to the Python→Go parity diff (Parser 1.8–1.11, 1.15).
