feat(inbox): bulk-remove yourself as a suggested reviewer

[rafaeelaudibert]

Problem

When triaging the Self-driving inbox, you can already bulk-snooze, suppress, reingest, and delete selected reports — but there was no way to bulk-remove yourself as a suggested reviewer. If you were suggested on a batch of reports that aren't yours, the only option was to open each one and remove yourself from its Reviewers section.

Changes

Adds a "Remove me as reviewer" action to the inbox bulk-selection toolbar.

• Reuses the existing per-item bulk fan-out (Promise.allSettled, partial-failure tolerant): per selected report it fetches the latest suggested_reviewers artefact, drops the current user's entry, and writes the remaining list back (the artefact PUT replaces the whole list).
• Eligibility uses the server-annotated is_suggested_reviewer flag, so the button disables (with a reason) when no selected report lists you as a reviewer — and only reports that actually list you get an API call.
• Fires one INBOX_REPORT_ACTION (remove_suggested_reviewer) per succeeded report, and reconciles the selection like the other bulk actions.

How did you test this?

• pnpm --filter @posthog/ui typecheck and pnpm --filter @posthog/core typecheck — pass.
• pnpm --filter @posthog/core test engagement — pass (added a case covering the new remove_suggested_reviewer bulk action type).
• biome check on the changed files — clean.

Prompt To Fix All With AI

### Issue 1
packages/ui/src/features/inbox/hooks/useInboxBulkActions.ts:443-444
**No-op removals count as success**

When the artefact is absent or contains no matching UUID, this callback resolves without updating anything, so `runBulkAction` records the report as succeeded and the UI emits success analytics, shows a success toast, and removes it from the selection even though the reviewer remains.

### Issue 2
packages/ui/src/features/inbox/hooks/useInboxBulkActions.ts:449-453
**Replacement writes lose concurrent updates**

When another reviewer edit completes between this action's artefact GET and PUT, this full-list replacement writes the stale snapshot without any version guard, causing the concurrent reviewer addition or removal to be overwritten.
