On the current CoA Beta client, C_ClassInfo.GetAllSpecs(class) returns
items that GetSpecInfo cannot accept as arg #2, throwing
'Script::ValidateInput Invalid argument type at index 2. Expected string.'
~150 times per session across DF, LibOpenRaid, gears, profiles, etc.
Wrap every unguarded GetSpecInfo(class, spec) site in pcall + nil-guard
so the iteration skips bad entries silently. Matches the pattern already
used by CoaExporter and prevents Error.txt flooding.
