Subject: [PATCH 1/5] Fix IT classes that are never executed in CI

The sharded CI jobs built their failsafe.includesFile by grepping the
source files for the category name, which misses classes that only
inherit their @Category; the Windows 1C1D shards skipped seven of them.
Build the lists from every class that failsafe picks up by default, as
fully qualified names, and leave the category selection to the profile.

Ten classes had no category, so no profile ran them; give them the
categories of their neighbours. Rename IoTDBActiveRegionScanIT2,
IoTDBActiveRegionScanWithModsIT2 and IoTDBTableViewAddColumnTest, whose
names failsafe does not pick up.

Fix what failed once these tests ran:
- The schema quota tests did not wait long enough for a schema change to
  reach the quota (two heartbeat rounds), and not at all between test
  methods that share a cluster.
- Since #18533 a table-model tablet whose FIELD columns are all null is
  rejected with 507; IoTDBSessionCompressedIT now asserts that.
- Ignore IoTDBClusterMixQuotaIT#testClusterSchemaQuota2: auto-extending a
  device template checks the quota only against the receiving DataNode's
  devices, so the test fails with several DataNodes.

Subject: [PATCH 2/5] Share the IT shard list script between the sharded CI
 jobs

The seven sharded jobs of cluster-it-1c1d.yml, table-cluster-it-1c1d.yml
and pipe-it.yml built their failsafe.includesFile with copies of the
same pipeline. Move it to .github/scripts/build-it-shard-list.sh so that
it is maintained in one place. The script writes the same lists, and
fails instead of writing an empty list, for which failsafe would fall
back to its default includes and run every class of the profile.

Subject: [PATCH 3/5] Read the quota IT heartbeat interval from the cluster

waitForSchemaQuotaUpdate took the heartbeat interval from
ConfigNodeDescriptor in the test JVM, which holds the default rather
than the configuration of the cluster's ConfigNode. Read the
heartbeat_interval_in_ms that the seed ConfigNode applies with
SHOW ALL CONFIGURATION instead.

Subject: [PATCH 4/5] Run the IT methods that no test profile selected

IoTDBCreateAlignedTimeseriesIT, IoTDBSessionComplexIT,
IoTDBSessionSimpleIT and IoTDBCustomizedClusterIT put @Category on
their test methods, and nine of these methods had none, so no test
profile ran them. Give them the categories of their neighbours:
LocalStandaloneIT and ClusterIT, and DailyIT in
IoTDBCustomizedClusterIT.

IoTDBCustomizedClusterIT#testStartWithWrongConfig compared the exit
value of the DataNode process with ILLEGAL_PARAMETER (303), which only
holds on Windows: POSIX systems keep only the low 8 bits of an exit
status, so a DataNode that exits with 303 reports 47. Compare the low
8 bits.

Subject: [PATCH 5/5] Check in CI that every IT runs

Add .github/scripts/check-it-selection.py, which fails when a test
class has a name that failsafe does not pick up, when a test method has
no @Category of its own, of its class or of a superclass, or when the
lists of build-it-shard-list.sh do not cover every candidate class
exactly once. It scans the sources instead of compiling them, so the
Ubuntu job of cluster-it-1c1d.yml runs it before the build.
