feat(content-preview): forward monitoring dimensions [PREVIEW-225]

[ahorowitz123]

Summary

Accepts three new optional props on <ContentPreview> — accessPattern, previewMode, sharedLinkAuth — and threads them into previewOptions so the underlying Preview library can tag emitted preview_metric / preview_error events for the monitoring dashboard.

Why

Part of the Preview Performance Monitoring dashboard rollout under WEBAPP-53337. The dashboard needs to slice TTPL by access pattern, preview mode, and shared-link auth. Companion box-content-preview work (accepting + emitting these dimensions) landed in PREVIEW-224; host app call sites land in PREVIEW-226 and PREVIEW-227.

Ticket

PREVIEW-225

Test plan

• Unit test: props forward to preview.show() options when supplied
• Unit test: options are undefined when props omitted
• Full ContentPreview test suite passes (147 tests)
• ESLint clean
• Manual verification: host app sets the props and confirms payloads carry the dimensions (tracked by PREVIEW-226/227)

🤖 Generated with Claude Code

Summary by CodeRabbit

• New Features
  • Content preview accepts three new optional settings: access pattern, preview mode, and shared-link authentication to refine preview behavior.

Walkthrough

ContentPreview Props gain three optional monitoring fields (accessPattern, previewMode, sharedLinkAuth); loadPreview destructures and forwards them into the options passed to preview.show. Tests assert the fields are present when provided and undefined when omitted.

Changes

Tests src/elements/content-preview/__tests__/ContentPreview.test.js	Adds tests asserting the monitoring dimensions are forwarded into preview.show options when provided and are undefined when omitted; removes a malformed trailing gap in prior tests.

Poem

🐰 I nudged three props into preview's song,
Softly forwarded where options belong.
Tests hopped in, checked both yes and none,
Metrics now ready — the work is done. 🥕
