New Zonation/Formation Names source WELL_PICKS_NO_TRAJECTORY resolves zone
depths directly from a well-picks file + well name, for tracks without a well
path (e.g. RFT plots without a trajectory). Kept strictly separate from the
existing WELL_PICK_FILTER (well-path-based) source so neither falls back into
the other's resolution path. RFT plots automatically select this source when
no well path exists but a matching well-picks file is found.
Also avoids including RiaWellLogTrackDefines.h from header files; the affected
headers now use opaque enum forward declarations, with the real definitions
included only in the .cpp files that need the enumerator values.
