Merge branch 'pratik/otel-phase10-workload-validation' into pratik/otel-sync-diagnostics

Phase-10 brought in the upstream nodestore/peerfinder/consensus reorganisation
along with its own write-path telemetry, which collided with the sync-diagnostic
signals on this branch. Twelve files conflicted; every resolution keeps both
intents rather than picking a side.

The nodestore write timing was implemented twice, independently. Both sides
added getStoreDurationUs()/getFetchDurationUs() to Database and both timed the
backend call in each concrete store(). Keeping both would have added twice to
storeDurationUs_ per store while storeStats() still counted one, so the mean
write latency would have read double on every dashboard -- silently, since no
test on either side asserts an exact microsecond figure. Resolved to one
accumulator API: recordStoreDuration(), which takes a duration, clamps a
sub-microsecond sample to zero and uses a relaxed atomic add. Phase-10's
storeDurationStats() is gone and its two call sites now use the survivor, so
all three store paths -- both store() overrides and importInternal() -- add
exactly once.

SlotCensus and its pure virtual moved from src/xrpld/peerfinder/ to
include/xrpl/peerfinder/PeerfinderManager.h, following the Manager interface
upstream relocated. The xrpld header is now phase-10's makeConfig shim, and
Overlay.h, MetricMacros.cpp and the getSlotCensus() override chain point at the
new location. ConsensusSpanNames.h and peerfinder Slot.h/Config.h include paths
followed their headers into libxrpl the same way.

InboundLedger gained phase-10's AcquireStats counters next to this branch's
span activations in both the destructor abort path and done(); neither
displaces the other. nodestore_state keeps the constant-based name this branch
requires of it and phase-10's fuller description.

Upstream #7292 deleted src/test/nodestore/Database_test.cpp, which held this
branch's testDurationAccessors. Phase-10 restored the per-store half of that
coverage in DatabaseConfig_test, but nothing covered importInternal -- it writes
through storeBatch() and never through store(), so it is a third store path that
has to time itself. That half is ported to a GTest in
src/tests/libxrpl/nodestore/Database.cpp, keeping the exact zero-before and
accumulate-after assertions and the per-instance negative check.
