Summary

• Add interactive release settings sections to the version detail page (below Localizations), visible only for non-terminal versions
• Version Release: radio group for Manual / After Approval / Scheduled release with datetime picker
• Phased Release: toggle 7-day gradual rollout with progress bar, day counter, and pause/resume/complete controls
• Rating Reset: toggle to reset app summary rating on release (write-only ASC API attribute, tracked with optimistic local state)
• Backend: PATCH version attributes, POST/PATCH/DELETE phased release endpoints with cache invalidation
• Version detail GET now includes phased release data via JSON:API include parameter

Test plan

• Navigate to a non-terminal version (e.g., PREPARE_FOR_SUBMISSION) and verify all three sections render
• Toggle release type radio buttons and confirm API call succeeds, detail refreshes
• Select SCHEDULED and set a date, verify date saves correctly
• Toggle phased release on/off, verify create/delete calls work
• Toggle rating reset, verify PATCH succeeds
• Navigate to a terminal version (READY_FOR_SALE) and confirm sections are hidden
• Test error handling: verify inline error messages appear on failure
• Test mobile layout: resize browser and verify responsive behavior
