[kevinchappell]

• fix: loadResources, multiple tooltip dom
• chore: update tests to work with new sprite logic

Pull Request Overview

This PR refactors SVG sprite handling from a DOM-injected approach to a bundled, in-memory approach for improved performance and reliability. The sprite is now bundled with the package and parsed in memory rather than fetched and inserted into the DOM. Icons are inlined when used, eliminating the need for xlink:href references.

Key changes include:

• Bundled SVG sprite using Vite's ?raw import instead of remote fetching
• In-memory sprite parsing with DOMParser instead of DOM insertion
• Icon inlining by cloning symbol children directly into SVG elements
• Removed unused component-corner icon and related styles
• Updated test infrastructure to support bundled sprite in Node.js environment
• Fixed multiple tooltip instantiation by creating single global instance
