* fix(server): describe EXPLAIN statements so bind parameters work
`do_describe_inner` only planned `Insert`/`Query`/`Delete`, so
`EXPLAIN` and `EXPLAIN ANALYZE` fell through to the non-plan branch
and had no parameter-type inference. At Bind time the Postgres
handler then reported `unsupported_parameter_type` even though the
inner query would have worked on its own.
Recurse one level into `Statement::Explain` so that an EXPLAIN
wrapping a plannable statement goes through the same describe path.
Adds a tokio-postgres integration test that exercises
`EXPLAIN`/`EXPLAIN ANALYZE` over the extended query protocol.
Fixes#8029

* refactor(server): extract plannable-inner check into closure
Reduce duplication between the direct match and the EXPLAIN inner match
by factoring out is_inner_plannable. Behaviour unchanged.

Add the `FLUSH_ELAPSED` histogram metric to track the duration of pending
rows batch flushes in the Prometheus store protocol handler. This provides
better observability into the performance and latency of the batcher.
Also update telemetry by:
- Recording elapsed time for both successful and failed flush operations.
- Adding an informational log upon successful flush including row count and duration.
- Including elapsed time in error logs when a flush fails.

* feat(servers): implement columnar batching for pending rows
Refactor PendingRowsBatcher to use columnar batching for the metrics
store. Incoming RowInsertRequests are now converted to RecordBatches,
partitioned, and flushed via BulkInsert requests to datanodes.

- Add metrics for tracking flush failures and dropped rows.

* feat(servers): add backpressure for pending rows
Implement backpressure in PendingRowsBatcher by limiting in-flight

- Add max_inflight_requests to PromStoreOptions.
- Use oneshot channels to notify submitters of flush completion.
- Limit concurrent requests using a new inflight_semaphore.
- Update PendingRowsBatcher::submit to wait for the flush outcome.

* perf(servers): use arrow builders for row conversion
This commit optimizes the conversion from `api::v1::Rows` to `RecordBatch`

in the `pending_rows_batcher`.
Additionally, the `#[allow(dead_code)]` attribute is removed from
`modify_batch_sparse` in the metric engine as it is now utilized.

- For RaftEngine variant, it doesn't actually allocate anything

- Rename `WalOptionsAllocatorRef` to `WalProviderRef`
- Rename `build_wal_options_allocator` to `build_wal_provider`

This commit implements the region allocation phase of the repartition procedure,
which handles allocating new regions when a table needs to be split into more partitions.
Key changes:
- Refactor `RegionRoutesAllocator::allocate` to accept `(region_number, partition_expr)` tuples
for more flexible region number assignment
- Simplify `AllocationPlanEntry` by removing `regions_to_allocate` and `regions_to_deallocate`
fields (now derived from source/target counts)
- Add `convert_allocation_plan_to_repartition_plan` function to handle allocation, equal,
and deallocation cases
- Fix `RepartitionPlanEntry::allocate_regions()` to return target regions (was incorrectly
returning source regions)
- Implement complete `AllocateRegion` state with:
- Region route allocation via `RegionRoutesAllocator`
- WAL options allocation via `WalOptionsAllocator`
- Operating region registration for concurrency control
- Region creation on datanodes via `CreateTableExecutor`
- Table route metadata update
- Add `TableRouteValue::max_region_number()` helper method
- Add comprehensive unit tests for plan conversion and allocation logic
