feat(explorer): Display checkpoint, epoch, and date on package details page with two-column layout (#9730)

# Description of change

Package details pages now display the checkpoint number, epoch, and
publish date from the package's creation transaction in a two-column
responsive layout. This provides developers with temporal context about
package deployment while using less vertical space.

## Changes

- **Modified
`apps/explorer/src/pages/object-result/views/PkgView.tsx`**:
- Added three new fields to the Details panel: Checkpoint, Epoch, and
Date
- Imported `formatDate`, `CheckpointSequenceLink`, and `EpochLink`
components
  - Implemented responsive two-column grid layout for the Details panel
  - Left column displays: Object ID, Version, Publisher
  - Right column displays: Checkpoint, Epoch, Date
  - Layout is responsive and stacks to single column on mobile devices

The implementation reuses the existing `useGetTransaction()` call that
fetches the package's creation transaction data.

### Layout Preview

![Package Details Two-Column
Layout](https://github.com/user-attachments/assets/5f000d6a-6aa1-49cc-9839-b49a10b129be)

**Layout benefits:**
- Two-column grid reduces vertical scrolling
- Logical grouping: static package info on left, temporal info on right
- Responsive design adapts to screen size (single column on mobile)
- All fields are clickable links where applicable

Example of what's now displayed:
```
Left Column:              Right Column:
- Object ID              - Checkpoint: 39,641,209 (link)
- Version                - Epoch: 99 (link)
- Publisher              - Date: 24 Feb, 15:11
```

## How the change has been tested

- [x] Basic tests (linting, compilation, formatting, unit/integration
tests)
- [x] Patch-specific tests (correctness, functionality coverage)
- [ ] I have added tests that prove my fix is effective or that my
