ENG-1608: Add command to create Base view for a node type

[trangdoan982]

https://www.loom.com/share/32a36f135ea74cbaaaf06de57ad54da3

Summary

• Adds a "Create Base view for node type" command that generates a .base YAML file filtered by nodeTypeId, making it easy to create table views for any node type without needing to know the cryptic auto-generated ID
• Three entry points: command palette, node type settings page, and discourse context panel
• Always creates a new .base file (with incrementing suffix if name exists) to avoid routing users to a modified Base view with stale filters

Test plan

• Command palette: Open command palette → "Create Base view for node type" → select a node type → verify .base file is created with correct nodeTypeId filter and opens
• Duplicate handling: Run the command again for the same node type → verify it creates a new file with suffix (e.g., "Claim Nodes 1.base")
• Settings: Go to Settings → Node Types → click a node type → click "Create Base view" → verify same behavior
• Settings guard: Add a new unsaved node type → verify "Create Base view" button is not shown
• Context panel: Open a discourse node → in the Discourse Context panel, click the layout-list icon next to the node type badge → verify same behavior
• Existing node type menu: Open command palette → "Open node type menu" with text selected → verify the node type picker still works for creating discourse nodes
• Base view works: In the opened .base file, verify Obsidian shows a table with only nodes of that type
