hermes - 💡(How to fix) Fix [Feature] Gallery modal should support horizontal navigation, caption editing, and high-res previews

Feature Description

The mobile gallery/detail modal should support core gallery workflows: navigate between items, edit captions, and view high-resolution previews.

Motivation

The current gallery/detail experience appears limited and cramped. The screenshot annotation requests:

• "Should be able to scroll gallery left and right"
• "and edit captions"
• "Also should be higher res."

Without this, users cannot efficiently review generated thumbnails/cards, correct captions, or inspect outputs at readable quality.

Proposed Behavior

In the gallery/modal view:

• Allow horizontal swipe/arrow navigation between gallery items.
• Show a clear position indicator, e.g. 4 / 6.
• Allow editing captions from the gallery/detail view.
• Display high-resolution previews instead of low-res thumbnails.
• Keep close/back controls accessible without covering content.
