Sami Khan ffacabe7e4 Fix uninstall button error (#1306) ...

## Motivation

Fix "Network setup script failed" error when clicking uninstall button
and resolve Xcode compiler warnings.

## Changes

- NetworkSetupHelper.swift: Add || true guards and explicit return 0 in
find_and_enable_thunderbolt_bridge to prevent script failures with set
-euo pipefail
- ThunderboltBridgeService.swift: Use withCString and
withUnsafeMutablePointer for Authorization API calls to fix pointer
lifetime warnings
- EXOApp.swift: Mark showNotification as nonisolated to fix main actor
isolation warning

## Why It Works

- The uninstall script's Thunderbolt re-enable function could exit
non-zero in edge cases (no bridges, no matches). Since this is a cleanup
step, failures should not abort uninstall.
- Swift requires explicit pointer lifetime management when passing
strings/structs to C APIs.
- showNotification is called from a nonisolated delegate method and uses
thread-safe APIs.

## Test Plan

### Manual Testing
Hardware: MacBook Pro

- Clicked Uninstall button, verified it completes without error
- Built in Xcode, verified no warnings   

### Automated Testing
