feat(ci): add Native AOT multi-platform release workflow

[crodriguesbr]

Description

Update the release workflow to use Native AOT compilation for multi-platform builds and add UX improvements to the dashboard.

CI/CD Changes:

• Replace PublishSingleFile + PublishTrimmed with PublishAot=true
• Add build targets for linux-x64, linux-arm64, win-x64, osx-x64, osx-arm64
• Add cross-compilation toolchain for Linux ARM64 builds

UI/UX Improvements:

• Add toast notifications for non-blocking feedback messages
• Add styled alert modals to replace browser alert() dialogs
• Add file upload option for request body with drag & drop support
• Add test mode toggle (By Requests / By Duration) for Quick Test and Endpoints

Bug Fixes:

• Fix sidebar resize layout issues using CSS variables
• Fix authentication token prefix spacing
• Fix token path extraction to support JSONPath syntax ($.access_token)

Code Quality:

• Remove all code comments for cleaner codebase

Motivation and Context

Native AOT provides faster startup times, smaller binary sizes, and better runtime performance compared to the previous self-contained single-file approach. The UI improvements enhance user experience with modern notification patterns.
