feat(ingest): route DOCX/XLSX/PPTX/images through docmark (ADR-0013)
Wires the sovereign docmark MCP server (git.d-ma.be/mathias/docmark) as the
converter for formats ingestion previously couldn't handle at all -- DOCX,
XLSX, PPTX, PNG/JPG. A single self-contained tools/call POST (docmark runs
stateless_http, no session handshake needed) does the conversion.

- internal/extract/docmark.go: extractViaDocmark(path) -- reads DOCMARK_URL +
  DOCMARK_BEARER_TOKEN from env, base64-encodes the file, calls docmark's
  convert_to_markdown tool, surfaces tool/HTTP errors with context.
- internal/extract/extract.go: routes .docx/.xlsx/.pptx/.png/.jpg/.jpeg to it.
- internal/api/handler.go: isSupportedExtension() replaces the static
  supportedExtensions map -- the new extensions are gated on DOCMARK_URL being
  set, checked per-request. When DOCMARK_URL is unset (e.g. this repo's
  current deployed state), behavior is byte-for-byte unchanged from today:
  same 400/silent-skip as before. Zero risk until the env var is actually
  wired in infra.

TDD throughout: docmark.go tested via httptest mock (success, not-configured,
tool-error, HTTP-error, all 6 new extensions route correctly); handler-level
test proves the DOCMARK_URL gate (docx 400 when unset, 200 when a working
mock is configured). Full task check green (fmt/vet/govulncheck/all tests).
