fix: keep bare numbered levels as ordered markers

[chriscoveries]

Summary

• Treat a bare lvlText="%n" ordinal as reproducible by the list item's native Markdown marker.
• Preserve restarted/complex numbering values while avoiding - 1 serialization for decimal, alphabetic, and roman ordered levels.
• Add a generated minimal DOCX fixture covering 1, 2 -> interruption -> 9 through startOverride, plus a snapshot.
• Update the existing ODT bare-number snapshot, which now emits ordered markers instead of bullet text.

Reproduction

Before this change, a DOCX level defined as numFmt="decimal" + lvlText="%1" rendered as:

- 1 First numbered paragraph.
- 2 Second numbered paragraph.

Heading break

- 9 Ninth numbered paragraph.

With this change it renders as:

1. First numbered paragraph.
2. Second numbered paragraph.

Heading break

9. Ninth numbered paragraph.

The distinction matters for legal/court exports that use Word auto-numbering with bare ordinals; the previous output preserved the values but encoded them as bullet text rather than Markdown ordered-list items.

Test plan

• cargo fmt --check
• cargo test -p anydoc
• Verified the new fixture snapshot and the existing handmade-lists.odt snapshot.

Summary by cubic

Fixes rendering of DOCX/ODT list levels that use a bare ordinal pattern (lvlText="%1") so they emit Markdown ordered markers (1.) instead of bullet text (- 1). Restarted and non-decimal ordinals are preserved. Adds a DOCX fixture covering an interrupted restart and updates the ODT bare-number snapshot.
