Feature: Show images with all the associated tags

**Is your feature request related to a problem? Please describe.**
Currently, RefreshImages() only uses the first tag of an image, which causes other valid tags to be ignored. This makes difficult to see or work with images that are referenced under multiple tags (e.g., nginx:1.25.0, nginx:stable, nginx:latest).

**Describe the solution you'd like**
Store and expose all image tags for each image instead of just the first one.

**Describe alternatives you've considered**

- Returning multiple Image objects for the same image ID (one per tag).
- Keeping the current single Tag but adding an Aliases []string field.

**Additional context**
This change would help users better understand and manage their images when multiple tags are used.
