jedarden b64ef6844d P2.4 Index lifecycle endpoints: implementation verification
Fixes:
- Removed #[axum::debug_handler] from search_handler to fix Send trait issue
  (EnteredSpan is not Send, causing compilation error)
- Updated p2_phase2_dod.rs tests to use new plan_search_scatter signature
  (async function with additional replica_selector parameter)
- Removed unused imports

The P2.4 implementation was already complete in indexes.rs and keys.rs:
- POST /indexes creates index on every node with rollback on failure
- PATCH /indexes/{uid}/settings sequential broadcast with rollback
- DELETE /indexes/{uid} broadcasts to all nodes
- GET /indexes/{uid}/stats aggregates logical doc count (divided by RG*RF)
- POST/PATCH/DELETE /keys broadcasts with rollback

All tests pass:
- p24_index_lifecycle: 11/11 tests pass
- p2_phase2_dod: 14/14 tests pass
- miroir-proxy lib: 135/135 tests pass
