fix: [PR-820] finish updating read paths where zone is available

[sigmachirality]

Where zone/cluster information is available, we want to make sure to show it to the user to encourage them to think in terms of zones as much as possible.

Greptile Summary

This PR completes the zone information display by adding zone fields to read paths (contracts and orders) and ensuring the zone from quotes is used in node creation when no zone is explicitly specified.

Key Changes:

• Added zone field to contract types and display
• Added cluster field (which represents zone name) to order types and verbose display
• Modified node creation to use zone from quote if available and no zone was specified
• Added --verbose flag to sf orders ls command to show expanded details including zone

Technical Note:
The API returns zone information as cluster for orders (type market-api_ClusterName) and zone for contracts. Both represent the same concept - the zone/cluster where resources are located. The display layer correctly shows "zone" to users while respecting the underlying API field names.

Confidence Score: 5/5

• This PR is safe to merge with minimal risk
• The changes are straightforward additions of zone information to display components and a defensive zone assignment in node creation. No existing logic is modified, only new fields and display elements are added. The code follows existing patterns and uses safe fallback values (N/A) for optional fields.
• No files require special attention

Important Files Changed
