Protocol 28 GA: core 28.0.0, SDK P28 pseudo-version

Both core pins (CAPTIVE_CORE_DEBIAN_PKG_VERSION, STELLAR_CORE_VERSION) move
to 28.0.0-3486.2332980a1.noble. go-stellar-sdk bumps to the P28 GA merge
commit pseudo-version; the load-test backend adapts to the SDK's new
multi-bundle LedgersFilePaths API (go-stellar-sdk#5959). CHANGELOG v28.0.0.
