Feat: Right click action feature for image to perform many actions

### Describe the feature

# Add Context Menu (Right-Click) Actions for Images

## Description

Currently, PictoPy allows interaction with images mainly through hover-based UI actions.
This enhancement introduces a **right-click context menu** on image cards to provide quick access to common image actions, improving usability and delivering a more desktop-native experience—especially important for the offline Tauri application.

## Proposed Context Menu Actions

When a user right-clicks on an image, a context menu should appear with the following options:

- Add to Album
- Favourite / Unfavourite
- Rename Image
- Share Image
- Copy Image to Clipboard
- View Image Info
- Delete Image

## Behavior Details

- Context menu opens on right-click of an image card
- Clicking a menu item does **not** trigger image selection
- All actions work in an offline Tauri environment
- Clipboard copy uses `convertFileSrc` for Tauri compatibility
- Share action falls back to copying the image path if `navigator.share` is unavailable
- Some actions (Rename, Delete, Add to Album) currently display **“Coming Soon”** dialogs

## UI / UX Notes

- Uses the existing `ContextMenu` component
- Icons provided via `lucide-react`
- Keyboard accessible
- Visual styling consistent with current dark/light themes
