dhi: refresh how-to explore

[craig-osterhout]

Description

• Refreshed explore based on latest GUI. Removed steps with a direct link. xref'd to previous sections to remove redundant steps.
• Consolidated explore and compare to minimize left nav sprawl and because they're related use-cases.
• Renamed from "explore" to "search" in order to not conflict with the about section that got renamed explore.
• Added in CLI commands to eventually remove the bolted-on, standalone how-to cli topic.
• Cleaned up some fluff from the compare topic that was used to make it feel more substantial when it was a standalone.

Assessment: 🟢 APPROVE

This PR successfully consolidates the DHI explore and compare functionality into a single, well-structured how-to guide. The changes follow Docker documentation style guidelines consistently:

✅ Style compliance: No AI-isms, hedge words, or meta-commentary
✅ Voice: Uses "you" and "select" appropriately
✅ Redirects: Proper alias added for the removed /dhi/how-to/compare/ page
✅ Front matter: All required fields present (title, description, keywords)
✅ Markdown: Code blocks properly balanced, no formatting issues
✅ Scope: Changes match the document's character - consolidation reduces nav sprawl while preserving content

The consolidation makes sense from a UX perspective - searching and comparing are related workflows that benefit from being on the same page.

Minor observation (not blocking): Several internal links throughout the codebase still reference /dhi/how-to/compare/ rather than pointing directly to /dhi/how-to/explore/. While the alias ensures these links work correctly, updating them to point directly to the new location would follow best practice for internal link management. This is purely a housekeeping suggestion and doesn't affect functionality.

I didn't find any other /how-to/compare/ via search.
