* feat(servers): add metrics and logs for pending rows batch flush
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.
- Enhance MultiDimPartitionRule to handle scalar boolean predicates.
- Add metrics for tracking flush failures and dropped rows.
- Update dependencies to support columnar batching in servers.

* feat(servers): add backpressure for pending rows
Implement backpressure in PendingRowsBatcher by limiting in-flight
requests with a semaphore and making the submission wait for the flush
result. This ensures Prometheus write requests are throttled and only
return once the data has been successfully flushed to datanodes.
- 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.

* feat: add stage-level metrics for bulk ingestion
Introduce histograms to track the elapsed time of various stages in the

This provides better observability into the performance bottlenecks
of the ingestion pipeline.

* - `src/metric-engine/src/engine/bulk_insert.rs`: Removed the fallback mechanism that converted record batches to rows when bulk inserts were unsupported, along with related helper functions and unused imports.

* feat(servers): columnar Prom remote write
Optimize the Prometheus remote write path by allowing direct conversion
from decoded Prometheus samples to Arrow RecordBatches. This bypasses
intermediate row-based representations when `PendingRowsBatcher` is
active and no pipeline is used, improving ingestion efficiency.
- Implement `as_record_batch_groups` in `TablesBuilder` and `PromWriteRequest`.
- Add `submit_prom_record_batch_groups` to `PendingRowsBatcher`.
- Introduce `DecodedPromWriteRequest` in `prom_store`.
- Implement row-to-RecordBatch conversion logic in `prom_row_builder`.

This reverts commit efbb63c12a3e7fcec03858ea0351efd94fec8242.
* refactor(servers): improve row to RecordBatch conversion
- Use `snafu::ensure` for row validation in `rows_to_record_batch`.
- Add explicit type hint for `MutableVector` to improve clarity.
- Reorganize and clean up imports in `pending_rows_batcher.rs`.

* perf(servers): use arrow builders for row conversion
This commit optimizes the conversion from `api::v1::Rows` to `RecordBatch`
by using Arrow builders directly. This avoids the overhead of
`MutableVector` and `common_recordbatch`, leading to better performance
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.

* perf(metric-engine): optimize batch modification
Optimize `modify_batch_sparse` by reusing buffers, using Arrow

**Add Environment Variable for Batch Sync Control**
- `pending_rows_batcher.rs`: Introduced an environment variable `PENDING_ROWS_BATCH_SYNC` to control the synchronization behavior of batch processing. If set to true, the function will wait for the flush result; otherwise, it will return immediatel
with the total rows count.

### Commit Message
#### Refactor Prometheus Validation Mode
- **Replace `is_strict_mode` with `PromValidationMode` Enum:**
- Updated `HttpOptions` and related structures to use `PromValidationMode` enum instead of the boolean `is_strict_mode`.
- Modified functions and tests to accommodate the new enum, ensuring flexible validation modes (`Strict`, `Lossy`, `Unchecked`).
- Affected files: `server.rs`, `prom_decode.rs`, `http.rs`, `prom_store.rs`, `prom_row_builder.rs`, `proto.rs`, `prom_store_test.rs`, `test_util.rs`, `http.rs`.
- **Enhance UTF-8 String Decoding:**
- Introduced `decode_string` function to handle UTF-8 string decoding based on the selected `PromValidationMode`.
- Affected files: `proto.rs`, `prom_row_builder.rs`.
This refactor improves the flexibility and clarity of Prometheus request handling by allowing different validation strategies.
* feat/lossy-string-validation-in-prom-remote-write:
- **Add Prometheus Validation Mode Configuration:**
- Updated `config/config.md`, `config/frontend.example.toml`, and `config/standalone.example.toml` to include `http.prom_validation_mode` setting for Prometheus remote write requests.
- **Enhance Benchmarking for Prometheus Requests:**
- Modified `src/servers/benches/prom_decode.rs` to benchmark different Prometheus validation modes (`Strict`, `Lossy`, `Unchecked`).
- **Implement and Test String Decoding:**
- Added `decode_string` function and comprehensive tests in `src/servers/src/proto.rs` to handle string decoding with different validation modes.
