tsdb/head: wlog exemplars after samples (#13113) 
When samples are committed in the head, they are also written to the WAL.
The order of WAL records should be sample then exemplar, but this was
not the case for native histogram samples. This PR fixes that.

The problem with the wrong order is that remote write reads the WAL and
sends the recorded timeseries in the WAL order, which means exemplars
arrived before histogram samples. If the receiving side is Prometheus
TSDB and the series has not existed before then the exemplar does not
currently create the series. Which means the exemplar is rejected and lost.

codemirror-promql: Add request header to client (#13118) 
With this commit we make it possible to adjust the request headers sent
to Prometheus by the codemirror-promql extension. This enables
customizing the headers sent, without re-implementing the Prometheus
client completely.

Julien Pivotto 0fe34f6d78 Follow-up to #13060: Add test to ensure staleness tracking 
This commit introduces an additional test in `scrape_test.go` to verify
staleness tracking when `trackTimestampStaleness` is enabled. The new
`TestScrapeLoopAppendStalenessIfTrackTimestampStaleness` function
asserts that the scrape loop correctly appends staleness markers when
necessary, reflecting the expected behavior with the feature flag turned
on.

The previous tests were only testing end of scrape staleness.

Bryan Boreham e6c0f69f98 TSDB: Only pay for hash collisions when they happen 
Instead of a map of slices of `*memSeries`, ready for any of them to
hold series where hash values collide, split into a map of `*memSeries`
and a map of slices which is usually empty, since hash collisions are
a one-in-a-billion thing.

The `del` method gets more complicated, to maintain the invariant that
a series is only in one of the two maps.

add generic shrink function (#13001) 
Add `ReduceResolution` method to `Histogram` and `FloatHistogram`

This takes the original `mergeToSchema` function and turns it into a more generic `reduceResolution` function, which is the building block for the new methods.

The methods will help with addressing #12864.
