feat(record): printable export options for PDF and Word

[peroza]

Summary

• Adds a shared record printable-export modal (scope, orientation, PDF/Word) opened from a single Export Document button in data entry.
• Passes exportScope, entity UUIDs, and orientation through the record PDF/DOCX API.
• Adds designer Print tab for per-entity printOrientation.
• Includes design/plan docs for the feature.

Depends on

• arena-core#390
• arena-server#170

Note: After arena-server is merged and published, bump @openforis/arena-server in this PR (currently still ^1.3.27, same as master). Until then, full export options need a local linked arena-server.

Test plan

• Experimental features on → Export Document opens the modal
• Current page only: document/file title uses entity label; own-page children excluded
• Full survey: respects entity Print orientation (mixed portrait/landscape after server publish)
• PDF and Word both work from the modal
• Ambiguous nested page instance disables download with hint
• Designer Print tab saves/clears orientation (publish survey before export picks it up)
• No portal: / symlink changes in package.json / yarn.lock
