fix(maps): icons not showing

[dschmidt]

This works without opencloud-eu/web#1412 because the icons are inlined.
That PR will make sure this won't break even if the icon size is increased or the assetsInlineLimit is decreased.

Fixes #235

[Copilot]

Pull Request Overview

This PR refactors the icon loading mechanism in the web-app-maps package by importing icon assets directly through Vite's URL imports instead of using a static copy plugin with dynamically constructed paths. This eliminates the need for vite-plugin-static-copy and the associated asset path calculations.

Key Changes:

• Removed vite-plugin-static-copy plugin and its configuration from the Vite config
• Replaced dynamic path-based icon loading with direct imports using Vite's ?url suffix
• Removed the dirname utility usage and assetsBaseUrl calculation
