fix(historian): stamp a positive StorageRateMs on provisioned tags

GatewayTagProvisioner built HistorianTagDefinition without a StorageRateMs, so
the proto uint32 defaulted to 0. The gateway's EnsureTags maps StorageRateMs
straight to the AVEVA SDK's storageRateMs, which requires a positive value —
0 makes the SDK throw ArgumentOutOfRangeException ('Storage rate must be > 0 ms'),
so EVERY historized-tag auto-provision (the deploy-time IHistorianProvisioning
hook) silently failed at the gateway with failed=N.

Stamp DefaultStorageRateMs=1000 (matches the gateway's own live provisioner
convention; quantized 1000/5000/10000). Add a regression unit test asserting the
definition carries a positive rate, and set StorageRateMs on the live-suite's
inline definitions so the retype probe reaches a real EnsureTags.

Found via the R2-06 live gate against a real 0.2.0 gateway + AVEVA historian:
with this fixed, Float/Int2/UInt2/Int4/UInt4/Double all provision and the live
suite goes 3/6 -> 5/6. (Int1/Boolean remains blocked by the gateway histsdk's
ProtocolEvidenceMissingException for Int1 — a gateway-side type-support gap, not
this bug.)

Gateway driver unit 103/103.
