* fix: handle ErrTooOldSample as 400 Bad Request in OTLP and v2 histogram write paths

The OTLP write handler and the PRW v2 histogram append path were missing
ErrTooOldSample from their error type checks, causing these errors to
fall through to the default case and return HTTP 500 Internal Server Error.
This triggered unnecessary retries in OTLP clients like the Python SDK.

The PRW v1 write handler (line 115) and the PRW v2 sample append path
(line 377) already correctly handle ErrTooOldSample as a 400, and this
change makes the remaining paths consistent.

Also adds ErrTooOldSample to the v1 sample/histogram log checks so
these errors are properly logged instead of silently returned.

Fixes #16645

* fix: prevent stale exemplars leaking to histogram _sum/_count across data points (#18056)

In addHistogramDataPoints, exemplars assigned to the +Inf bucket of one
data point were carried over into the _sum and _count Append calls of
the next data point via the shared appOpts. Clear appOpts.Exemplars at
the start of each loop iteration to restore the nil-exemplar semantics
that existed before the AppenderV2 migration.

* tsdb: fix flaky TestBlockRanges by using explicit compaction

Replace polling loops (for range 100 { time.Sleep }) with explicit
db.Compact() calls after disabling background compaction, eliminating
CI flakiness on slow machines. Also fix incorrect overlap assertions
that were checking the wrong direction (LessOrEqual -> GreaterOrEqual).

* rules: fix flaky TestAsyncRuleEvaluation on Windows (#17965)

Convert all timing-sensitive subtests of TestAsyncRuleEvaluation to use
synctest for deterministic testing. This fixes flakiness on Windows
caused by timer granularity and scheduling variance.

The timing assertions are preserved using synctest's fake time, which
allows accurate verification of sequential vs concurrent execution
timing without relying on wall-clock time.
