Fix: Remove empty string elements from IDs slice in delete commands

[ramya18101]

🔧 Changes

Fixes a bug where delete commands across multiple resources were initializing IDs slice with empty strings when arguments were provided via CLI.

The pattern used in delete commands was:

ids := make([]string, len(args))  // Creates slice with len(args) empty strings
// ...
ids = append(ids, args...)         // Appends args after the empty strings
