Fix URL handling in pasteboard operations (#5029)

## Description
When pasting URLs from clipboard, the behavior varies based on the
source:

1. From browser address bar:

   - Pasteboard types: ["public.utf8-plain-text", "NSStringPboardType"]
   
   - Handled as plain text, resulting in correct full URL paste

2. From clipboard history tools, such as Raycast clipboard history:
   
   - Pasteboard types include "public.url" and related URL types
   
- URL was being processed through NSURL, which only extracted the path
component
   
   - This resulted in incomplete URLs

## Changes

- Modified `getOpinionatedStringContents()` to differentiate URL types:

- For file URLs (`file://`): preserve existing behavior, return path
only
  
- For web URLs (`http://`, `https://`): return full URL string via
`absoluteString`
  
  - For non-URL content: maintain existing plain text handling
