feat: replace thumbs up/down with 5-star rating UI

[bookwormsuf]

Problem

Part 5 of admin satisfaction rating split (see #9683, #9684, #9688, #9689). Replaces the old thumbs up/down feedback modal with a 1-5 star rating and wires triggerSource/formId through to the API.

Solution

AdminFeedbackBox rewrite — deleted 4 sub-components and state machine (218 lines), replaced with a single 148-line component using the existing <Rating> component. Stars render inline, and clicking a star immediately creates/updates the feedback record. An adaptive comment label changes based on rating: "What went wrong?" (1-2), "What could we improve?" (3), "What did you enjoy most?" (4-5).

API wiring — createAdminFeedback now accepts optional triggerSource and formId. updateAdminFeedback accepts { comment?, rating? } instead of just a comment string. The container captures trigger metadata from the zustand store via refs before reset clears it.

Joi tightening — create validation changed from min(0) to min(1). The old 0 value was the thumbs-down binary; the new star UI never sends 0.

Type cleanup — removed the deprecated AdminFeedbackRating enum, replaced with type AdminFeedbackRating = 1 | 2 | 3 | 4 | 5. AdminFeedbackBase.rating now uses this type instead of number.

Reviewer tip: review the new AdminFeedbackBox.tsx directly rather than following the diff. The old file was replaced entirely.

Breaking Changes

No - backwards compatible. The star UI is gated behind the 5star-admin-rating feature flag (PR 1).

Empty state	2 stars (low)	3 stars (mid)	5 stars (high)

Tests

TC1: Star rating renders and submits

• Enable feature flag: window._growthbook.setForcedFeatures(new Map([['5star-admin-rating', true]]))
• Trigger feedback (edit 5+ fields on a form)
• Verify stars render instead of thumbs up/down
• Click 3 stars, verify "What could we improve?" label appears
• Type a comment and submit
• Verify DB record has rating: 3, triggerSource: 'field-edit', formId set

TC2: Rating update works

• Click 2 stars, then click 5 stars before submitting comment
• Verify DB record has rating: 5 and ratingChanged: true

TC3: Adaptive labels

• Click 1 or 2 stars, verify "What went wrong?"
• Click 3 stars, verify "What could we improve?"
• Click 4 or 5 stars, verify "What did you enjoy most?"

TC4: Close without rating

• Open feedback modal, click X without selecting stars
• Verify no feedback record created
