ShowSkeets: Add thread connector to "See more" card
Wrap the "See more" button in a `Row` to include a vertical divider, visually connecting it to the post thread.
- Use a `VerticalDivider` with `outlineVariant` color and rounded corners to match thread styling.
- Adjust layout using `IntrinsicSize.Min` and a negative vertical offset for better alignment.
- Update `ConditionalCard` padding and weight within the new container.
