fix(driver-abcip): resolve High code-review findings (Driver.AbCip-001, -002, -003, -008)

Driver.AbCip-001 — ReinitializeAsync silently discarded its config JSON.
Extracted AbCipDriverFactoryExtensions.ParseOptions; InitializeAsync now
re-parses a content-bearing driverConfigJson and replaces _options (and
recreates the alarm projection), so a reinitialize with a changed config
(new device/tag, changed timeout) actually takes effect. A blank or
empty-object JSON keeps construction-time options for the unit-test seam.

Driver.AbCip-002 — libplctag status mapping used wrong integer constants.
MapLibplctagStatus now switches on the libplctag.NET Status enum members
(Ok/Pending/ErrorTimeout/ErrorNotFound/ErrorNotAllowed/ErrorOutOfBounds/…)
instead of hand-typed natives, so timeout/not-found/not-allowed/out-of-bounds
get their specific OPC UA codes instead of all collapsing to
BadCommunicationError. The int overload casts to Status to stay correct
against the wrapper's contiguous renumbering.

Driver.AbCip-003 — whole-UDT reads decoded members at declaration-order
offsets, which Studio 5000 does not guarantee. Added the opt-in
AbCipDriverOptions.EnableDeclarationOnlyUdtGrouping flag (default false);
AbCipUdtReadPlanner.Build forms no groups when it is off, so by default
every UDT member reads per-tag rather than at possibly-wrong offsets.

Driver.AbCip-008 — probe loops were fire-and-forget and ShutdownAsync raced
them. Each probe Task is stored on DeviceState.ProbeTask; ShutdownAsync now
cancels every CTS, awaits each probe Task (10s timeout), then disposes the
CTS and handles. DeviceState.Runtimes/ParentRuntimes are ConcurrentDictionary
and the Ensure*RuntimeAsync paths use TryAdd, disposing the losing concurrent
creator instead of leaking a native tag handle.

Adds AbCipDriverCodeReviewRegressionTests and updates existing AbCip tests
to the corrected status constants + opt-in grouping flag. AbCip driver +
test project build clean; all 244 AbCip tests pass. (The full-solution
build has pre-existing, unrelated Driver.Galaxy protobuf-generation errors
in this worktree.)
