fix(telemetry): resolve Clang build, clang-tidy, and rename CI failures

- Add [[maybe_unused]] to RAII span variables in PathFind/RipplePathFind
  handlers (Clang -Wunused-variable with -Werror)
- Restore over-renamed values: rippledb, rippled.cfg, historical GitHub URL
- Concatenate nested namespaces in SpanNames.h and PathFindSpanNames.h
  (modernize-concat-nested-namespaces)
- Add missing includes and const qualifiers in test files
- Suppress intentional use-after-move in SpanGuardFactory move test
- Remove unused NetworkOPs.h include from PathRequest.cpp
