When authoring Bicep modules from the public registry (AVM), the completion dropdown is too narrow for the long module paths. Most AVM paths share long prefixes (e.g., avm/ptn/...) and differ toward the end, so it's hard to visually scan the list. The problem gets worse at higher editor zoom levels.

Steps to Reproduce

• Open a Bicep file.
• Type: module test 'br/public: and trigger completions.
• Browse the AVM module list.
• Increase editor zoom (e.g., 120% or 150%) and repeat.

The suggest widget is narrow; long items truncate. The distinguishing part of the module path is hard to see, especially at higher zoom.

Expected Result

Completion list remains readable even with long module paths. Users can quickly identify items by their unique suffix (module name).

Describe the solution you'd like

• Suffix-first labels: show the tail segment as the main label, with the prefix in a dimmed description.
• Prefix de-emphasis using labelDetails.description.
• Keep full path as insertText while displaying a shorter label.
• Smarter sort/filter to prioritize suffix matches.
