merge: bring develop forward into phase-9 metric gap fill

Resolved five files.

PerfLogImp.cpp: PerfLog now takes its method names as string_view, so the
methods map stores the map key rather than a char const*. Kept this branch's
scoped lock so the OTel recording still runs after methodsMutex is released,
and kept both the NetworkOPs and metric-macro includes.

PeerImp.h: took develop's earlier `protected:`, which also covers
processLedgerRequest, and kept recordGetObjectMetrics inside it. Dropped the
comment naming one test, since four test files now rely on that access.

TMGetObjectByHash_test.cpp: kept this branch's suite. It already runs develop's
three bound cases (limit+1, limit, limit-1) as testReplyLimit, plus the charge
and hit/miss cases. develop's extracted PeerTest.h stays, used by its four new
overlay tests.

ordering.txt: regenerated. Both perflog edges are real, to xrpl.server and to
xrpl.telemetry.

.cspell.config.yaml: kept both added words.
