### Describe Your Changes
1. **Add new `Raw Query` tab**
A new `Raw Query` tab has been added to the
[vmui](https://docs.victoriametrics.com/#vmui) interface for displaying
raw data. The tab uses the `/api/v1/export` API endpoint. Related issue:
[#7024](https://github.com/VictoriaMetrics/VictoriaMetrics/issues/7024)
2. **Fix rendering of isolated points on the graph**
Previously, isolated points (not connected to other points on the left
or right) were not visible on the graph. Now, they are rendered
correctly.

Previously, for `^` aka pow function calls, VictoriaMetrics returned `1`
if left arg was Nan. For example, given query=`(hour()==2)^1` returns 1
for NaN produced by hour() == 2 function. It added additional non-exist
datapoints to the timeseries.
This commit port bugfix from `metricql` package and adds test for it.
Now, VictoriaMetrics
correctly returns `NaN` for such cases.

fixes#7579 7579
Previously, dedup was added as a downsampling rule with 0s offset to all downsmapling rules with filters. That enforced a metric name lookup even in cases it is not needed.
For example, the following configuration: `-dedup.minScrapeInterval=10s -downsampling.period={__name__=~"node.*"}:1h:1m` would be parsed as: `{__name__=~"node.*"}:1h:1m {}:0s:10s`
This commit changes this logic and treats dedup as a separate case. This allows to perform metric name lookups only in cases when timestamp of current partition can be eligible to use some of downsampling filters. Newer parts will not trigger metric name lookup and will apply deduplication directly.

After changes at commit 787b9cd. Minimal timestamps for extDB check was performed without context of the index search prefix.
It worked fine for Single node version, but for cluster version a different prefix was used for
metricID search requests. It may lead to incomplete results, if minimal missing timestamp was cached
for the tenant with different ingestion patterns.
Minimal reproducible case is:
- metrics were ingested for tenants 0 and 1
- at some point in time metrics ingestion for tenant 1 stopped
- index records have the following timestamps layout:
tenant 0: 1,2,3,4,5,6
tenant 1: 1,2,3,4
- after indexDB rotation, containsTimeRange lookups may produce
incorrect results:
time range request for tenant 1 - 5:6 caches 5 as min timestamp
request for the same or smaller time range for tenant 0 now returns
empty results.
Second case:
- requests for the tenant without metrics always updates atomic value with incorrect minimal time range for other tenants.
This commit replaces single atomic with map of search prefix keys. It should have slight performance overhead,
but work consistently for cluster version. minMissingTimestamp is cached by prefix search key, which included tenantID.
Since it will be only populated at runtime, it doesn't hold unused tenants for queries.

This commit fixes panic for multitenant requests and empty storage node responses for tenants api.
It also optimizes `populateSqTenantTokensIfNeeded` function calls, by making it only once for query request. Previously it was incorrectly called multiple times per each storage node request.

### Describe Your Changes
when migrating from cluster to single, the native export API attach
`vm_account_id` and `vm_project_id` labels.
`--vm-native-disable-binary-protocol` is a workaround to remove them,
which is available since v1.93.0 but did not documented in vmctl doc.

- The --delete option is needed to be passed to rsync during backups,
Since otherwise the backup may contain superfluous files after the second run of rsync,
because these files can be already removed at the source because of background merge
- the --delete option is needed when restoring from backup in order to remove superfluous files
from the destination directory. Otherwise these files may lead to inconsistent data at VictoriaLogs.
