feat: add useSpeedTestEndpoints hook to collect all endpoint candidates for speed test modal

- Create useSpeedTestEndpoints hook that collects endpoints from:
  1. Current baseUrl/codexBaseUrl
  2. Initial data URL (edit mode)
  3. Preset's endpointCandidates array
- Pass speedTestEndpoints to ClaudeFormFields and CodexFormFields
- Update EndpointSpeedTest to use collected endpoints instead of just current URL
- Fix PackyCode preset endpoints not appearing in speed test modal
