Joseph Doherty 205cc4a4a3 feat(galaxy): per-code OPC UA mapping for the MxStatusDetail vocabulary
Follow-up to 20a816db: mxaccessgw published the full MxStatusDetail enum
(gateway.md @ 75c71ad, "MxStatus Detail Vocabulary", lifted from
Interop.aaMxDataConsumer.MxStatusDetail), confirming the live-captured codes
(1007 = MX_E_NotWriteable, 1008 = MX_E_WriteAccessDenied). FromCategory now
maps the write-relevant band per code before falling back to the category
bucket: 1004 -> BadOutOfRange, 1005 -> BadTypeMismatch, 1006 -> BadNotReadable,
1007 -> BadNotWritable, 1008/1012/1013/1016/1017 -> BadUserAccessDenied,
1010/1011 (initializing, transient) -> BadOutOfService. 8000
(MX_E_AutomationObjectSpecificError) deliberately stays category-level — the
object supplies its own semantics. Codes <= 0xFF are value-ambiguous with the
OPC DA quality-byte space and keep the quality path (still Bad-family).

Four new named constants, all validated by StatusCodeParityTests against the
pinned SDK. Live refusal smoke re-run green (read-only refusal now surfaces
BadNotWritable instead of generic Bad).
