The catalog had S14F9/F10 / F11/F12 specialized for E94 ControlJob;
this commit adds the generic E14 attribute access pair, the most-
queried half of the E39 surface area, backed by the CemObjectStore.
S14F1 / F2 GetAttr — OBJSPEC + OBJTYPE + ATTRID list ->
(ATTRID, VALUE) pairs + OBJACK
S14F3 / F4 SetAttr — same addressing, applies ATTRID/VALUE pairs,
reply echoes stored values + OBJACK
Server dispatches both into the CemObjectStore added in tranche G.
OBJTYPE validation is case-sensitive against the CemObjectType name
(Equipment / Subsystem / IODevice / Module / MaterialLocation).
Unknown objects return Denied_UnknownObject; type mismatches return
Denied_InvalidAttribute.
The shared AttrValue struct is declared external_struct: true on
F3/F4 so both directions share the same C++ type.
Two round-trip tests cover both pairs.
