The application was crashing with a panic when network errors (including TCP timeouts) occurred while fetching channels from the JioTV API. This issue manifested when the television.Channels() function encountered network connectivity problems, causing the entire server to terminate unexpectedly.

Root Cause

The Channels() function in pkg/television/television.go was using utils.Log.Panic(err) to handle network errors, which terminated the entire application instead of gracefully handling the error condition.

Solution

This PR implements proper error handling by:

1. Modified the Channels() function signature from func Channels() ChannelsResponse to func Channels() (ChannelsResponse, error) to allow error propagation
2. Replaced panic calls with proper error logging using utils.Log.Printf() and returning the error to the caller
3. Updated HTTP handlers (IndexHandler and ChannelsHandler) to handle the returned errors gracefully and respond with appropriate HTTP 500 error messages

Before (Problematic Behavior)

// Network error would cause application crash
resp, err := utils.MakeHTTPRequest(config, client)
if err != nil {
    utils.Log.Panic(err)  // 💥 Application terminates
}

After (Graceful Error Handling)

// Network error is handled gracefully
resp, err := utils.MakeHTTPRequest(config, client)
if err != nil {
    utils.Log.Printf("Error fetching channels from JioTV API: %v", err)
    return ChannelsResponse{}, err  // ✅ Error returned to caller
}

Benefits

• Server stability: Network errors no longer crash the entire application
• Better user experience: Clients receive proper HTTP 500 error responses with meaningful error messages instead of connection drops
• Improved debugging: Errors are logged for troubleshooting while maintaining server operation
• Minimal impact: Only essential changes made to core functionality

Testing

• All existing tests continue to pass
• Server remains responsive after multiple consecutive network failures
• Error logging works correctly in debug mode
• Proper HTTP error responses are returned to clients

Fixes #667.
