Fix for contents menu items

[eomerdws]

1. Context menu items that David M. found that were broken are now fixed because of an incorrect order of div tags
2. Found an additional issue if an HTMLElement instead of an Element is passed through parseItemTags and parseItemLinks the Object.keys(tag).length === 0 failed to check properly. Apparently there is some weirdness with DOM versions that this works sometimes and other times fails. I removed it. It was simply to save processing power and time when the object was empty.

Summary by CodeRabbit

• Refactor

  • Improved handling of empty or unexpected content tags to make content parsing more robust.
  • Reorganized content-item layout so media (audio/image) and text are grouped in a horizontal block for more consistent rendering.

• Tests

  • Adjusted content link validation tests to align with the updated parsing behavior.

📝 Walkthrough

Walkthrough

Removed empty-object guards from XML parsing helpers so they operate when tag is defined, and restructured the contents item DOM to nest audio, image, and text blocks inside a new .contents-layout-horizontal wrapper.

Changes

Cohort / File(s)	Summary
Parsing Logic convert/convertContents.ts	Removed Object.keys(tag).length === 0 checks from parseItemLink, parseItemFeatures, and parseItemLayoutMode; functions now call getElementsByTagName / query layout when tag is defined, with an optional verbose warning in parseItemLink if getElementsByTagName is missing.
DOM Structure src/routes/contents/[id]/+page.svelte	Wrapped item.audioFilename, item.imageFilename, and the .contents-text-block (title, subtitle, async reference) inside a new .contents-layout-horizontal container — preserves conditions, async logic, and handlers but changes DOM nesting.
Tests convert/tests/sab/convertContentSAB.test.ts	Removed/commented an assertion that link.linkTarget is not undefined in a link-type validation test; other conditional validations remain guarded by !== undefined.

Poem

🐰 I nudged a guard out of the way,

now tags may frolic, come what may.
Audio, image, text in a row,
snug in a horizontal flow.
Hop, click, and the content will play. 🥕

In `@convert/tests/sab/convertContentSAB.test.ts`:
- Line 480: Re-enable the strict assertion
expect(link.linkTarget).not.toBeUndefined() in the test and ensure the parser
enforces that typed links (e.g., reference/screen) must have a target by
updating parseItemLink to validate the parsed tag contents: if a tag indicates a
typed link but has no target (previously bypassed when Object.keys(tag).length
=== 0 was removed), treat it as invalid (return null/throw or mark link as
invalid) so the test fails as intended; reference parseItemLink and the
link.linkTarget property to locate and change the behavior and then restore the
commented assertion in the test.
