Fix Vite module resolution for apps with spaces in directory names

[Copilot]

Vite fails to resolve modules when project directories contain spaces, causing CodeGen End2End test failures with import errors, timeouts, and browser crashes.

Changes

• Added base: './' to React Vite config template
• Added base: './' to Web Components Vite config template

Technical Details

Without explicit base path configuration, Vite generates absolute paths that fail when directory names contain spaces (e.g., /My%20Test%20App/src/main.tsx). Setting base: './' forces relative path resolution, bypassing URL encoding issues.

Affected templates:

• packages/cli/templates/react/igr-ts/projects/_base/files/vite.config.ts
• packages/cli/templates/webcomponents/igc-ts/projects/_base/files/vite.config.ts

Before:

export default defineConfig({
  build: {
    chunkSizeWarningLimit: 10 * 1024 * 1024,
  },
  // ...
})

After:

export default defineConfig({
  base: './',
  build: {
    chunkSizeWarningLimit: 10 * 1024 * 1024,
  },
  // ...
})

This resolves failures in apps like "Colors (with parameters)", "User Story 2 (HData repeated)", and "Master-detail side by side".

Warning

Firewall rules blocked me from connecting to one or more addresses (expand for details)

I tried to connect to the following addresses, but was blocked by firewall rules:

• vite.dev
  • Triggering command: /home/REDACTED/work/_temp/ghcca-node/node/bin/node /home/REDACTED/work/_temp/ghcca-node/node/bin/node --enable-source-maps /home/REDACTED/work/_temp/copilot-developer-action-main/dist/index.js (dns block)
• www.google-analytics.com
  • Triggering command: /usr/local/bin/node node /home/REDACTED/work/igniteui-cli/igniteui-cli/packages/cli/bin/execute.js new My Test App --framework=react --type=igr-ts --skip-git (dns block)
  • Triggering command: /usr/local/bin/node node /home/REDACTED/work/igniteui-cli/igniteui-cli/packages/cli/bin/execute.js new My WC App --framework=webcomponents --type=igc-ts --skip-git (dns block)
  • Triggering command: /usr/local/bin/node node /home/REDACTED/work/igniteui-cli/igniteui-cli/packages/cli/bin/execute.js new normalapp --framework=react --type=igr-ts --skip-git _modules/.bin/ty168.63.129.16 (dns block)

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)

<issue_title>[React, WC]: Failing CodeGen End2End tests with errors in vitest</issue_title>
<issue_description>Currently, there are some failing apps when running CodeGen End2End tests

For React:

• Colors (with parameters)
• [WIP] Apex Charts
• [React] Grid Duplicate Columns - 31419
• User story 1 (with View container)
  Error: Failed to import test file; Vitest failed to find the current suite:
  https://github.com/IgniteUI/CodeGen/actions/runs/21430424883/job/61708262371

For React and Web Components:

• User Story 2 (HData repeated)
  Error: Failed to import test file; TypeError: Failed to fetch dynamically imported module:
  https://github.com/IgniteUI/CodeGen/actions/runs/21430356854/job/61708049989

• Grid + Form and User Story 0 (Combo/Select + Grid + Grid) (1)
  These apps failed because of timeout while running: https://github.com/IgniteUI/CodeGen/actions/runs/21430287462/job/61707831324

For Web Components:

• Master-detail side by side
  Error: [vitest] Browser connection was closed while running tests. Was the page closed unexpectedly: https://github.com/IgniteUI/CodeGen/actions/runs/21429568468/job/61727463017</issue_description>

<agent_instructions>The problems might be because of the spaces in the names of the apps. Probably changes in the vite configuration ?</agent_instructions>
