fix: validate response before using repo_id (#207)

[DevanshuNEU]

Summary

Fixes #207 - Frontend was sending /repos/undefined/index when the add repository API call failed.

Changes

• Check response.ok before parsing JSON response
• Validate repo_id exists before triggering index endpoint
• Errors now properly propagate to the catch block with meaningful messages

Before

const data = await response.json()
await fetch(`${API_URL}/repos/${data.repo_id}/index`, { ... })
// If first request fails, data.repo_id = undefined

After

if (!response.ok) {
  const err = await response.json().catch(() => ({}))
  throw new Error(err.detail || 'Failed to add repository')
}

const data = await response.json()
if (!data.repo_id) throw new Error('Missing repo_id in response')

await fetch(`${API_URL}/repos/${data.repo_id}/index`, { ... })

Testing

• Add repo with invalid URL → should show error toast
• Add repo exceeding tier limit → should show upgrade message
• Add valid repo → should work as before
