fix!(capture): move plain capture point past properties drawer

- Fix org-roam-capture--adjust-point-for-capture-type to properly handle
  cases where point is positioned after head content but not at a heading
- Remove redundant location-type logic that incorrectly assumed point > 1
  means we're at a heading (file+head can position point after keywords)
- Restore call to adjust-point-for-capture-type that was removed in ed94524
- Add comprehensive tests for plain capture ordering and assertion error fix
- Refactor adjust-point-for-capture-type for better readability
