* fix(prometheus): skip pending-row timeout fallback when batcher is disabled
PendingRowsBatcher::try_new returns None when max_batch_rows,
max_concurrent_flushes, worker_channel_capacity or max_inflight_requests
is zero, meaning remote writes bypass batching entirely. The timeout
fallback predicate now mirrors these enablement conditions so the HTTP
timeout is not raised when no request can wait for a pending-row flush.
Signed-off-by: Lei, HUANG <ratuthomm@gmail.com>
* fix(prometheus): skip pending-row timeout fallback in async batch mode
With PENDING_ROWS_BATCH_SYNC=false, pending-row submissions return right
after enqueue and no request waits for a flush, so raising the global
HTTP timeout only delays unrelated routes. Export the batch sync mode
predicate from the servers crate and consult it in the frontend's
effective_http_options so the fallback is skipped in asynchronous mode.

* fix: count Postgres SCRAM auth failures in the auth failure metric
The SCRAM SASL paths returned `Failed` without touching
`METRIC_AUTH_FAILURE`, so once SCRAM is enabled wrong-password and
unknown-user attempts disappeared from `greptime_servers_auth_failure_count`.
Funnel every SCRAM rejection through `record_scram_failure`, which records
one failure with a uniform `UserPasswordMismatch` label so the counter stays
useful without revealing whether the user exists.

* docs: correct per-protocol auth notes in config examples
The user_provider note no longer matched the implementation: pbkdf2_sha256
is excluded from Postgres SCRAM (so its iteration count is never exposed in a
SCRAM handshake), and the warning that hash-only verifiers cannot use MySQL's
native password handshake had been dropped.
State the actual per-protocol fallbacks and incompatibilities, scope the
iteration/salt enumeration caveat to pg_scram_sha256, and regenerate
config.md.

* fix: avoid double-counting Postgres SCRAM authorization failures
authorize() already increments METRIC_AUTH_FAILURE with its own status
code, so routing the authorization-rejection path through
record_scram_failure counted it twice, mislabeling the second increment
as UserPasswordMismatch. Return early to bypass the recorder.

- Verify the client-final nonce matches the server-issued nonce, per RFC 5802

- Replace the per-connection PBKDF2 over a random password for unknown users
with a deterministic mock verifier keyed by the username and a process-wide
secret. This avoids a CPU-exhaustion DoS on unknown usernames and removes a
username-enumeration oracle: the SCRAM server-first salt and iteration count
are now stable per username and indistinguishable from a real user, with no
PBKDF2 cost and random keys that never accept a proof.

* fix: precompute stable SCRAM verifier for plaintext users
Plaintext-backed credentials derived a Postgres SCRAM verifier on the fly
on every connection, using a fresh random salt and running PBKDF2 each
time. That made a known plaintext user distinguishable from stored-hash
and unknown (mock) users through both the unstable server-first salt and
the per-connection timing, enabling username enumeration.
Precompute the SCRAM verifier once at load time (stable salt, default
iteration count) and reuse it, matching the mock verifier handed to
unknown users. Document that non-default iteration counts remain
observable in the SCRAM handshake and weaken enumeration resistance.

Fixes#8087
FrontendOptions, DatanodeOptions, and FlownodeOptions do not define
a heartbeat field, so the [heartbeat] sections in their example TOML
files were never parsed.
Heartbeat intervals are actually negotiated from metasrv during the
heartbeat handshake:
- Datanode/Flownode: interval = metasrv.heartbeat_interval
- Frontend: interval = metasrv.heartbeat_interval * 6
This mislead operators into thinking they could tune heartbeat timing
locally. Remove the sections to eliminate confusion.
Metasrv's heartbeat_interval remains documented and functional.

### 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`).
