[BUG] List properties with links don't work

[Benna96]

Describe the bug

Can't add links to list-type properties without a manual workaround.

To Reproduce

1. Enable 'Format template variables as proper peroperty types (Beta)'
2. Run the following template to test a list containing a single link:

   ---
   authors: {{VALUE:authors}}
   ---
   ```js quickadd
   this.variables.authors = [`[[John Doe]]`];
   ```

3. Observe that the output is as desired, with " marks being added automatically:

   ---
   authors:
     - "[[John Doe]]"
   ---

4. Run the following template to test a list with multiple links:

   ---
   authors: {{VALUE:authors}}
   ---
   ```js quickadd
   this.variables.authors = [`[[John Doe]]`, `[[Jane Doe]]`];
   ```

Expected behavior
The following output:

---
authors:
  - "[[John Doe]]"
  - "[[Jane Doe]]"
---

Actual behaviour
The following output:

---
authors: [[John Doe]],[[Jane Doe]]
---

Workaround
Constructing the output myself as a string works:

---
authors: {{VALUE:authors}}
---
```js quickadd
this.variables.authors = `\n- "[[John Doe]]"\n- "[[Jane Doe]]"`;
```

Additional context
The setting Format template variables as proper peroperty types (Beta) is on.
The result is the same whether it's on or off, though.

Hey! Thanks for the report. I was able to reproduce this, and it’s now fixed in #1154.

The problem was that multi-value wikilink properties were being written into frontmatter in a form Obsidian could not correctly process. QuickAdd now keeps the frontmatter YAML-valid during template rendering and then lets Obsidian write the final structured property value back correctly.

This was verified with both unit coverage and an Obsidian-backed e2e regression test for cases like:

authors:
  - "[[John Doe]]"
  - "[[Jane Doe]]"

The fix has been merged to master and will be included in the next release.
