fix(driver-abcip): resolve Low code-review findings (Driver.AbCip-007,011,012,013,015)

- Driver.AbCip-007: inject an optional ILogger<AbCipDriver> /
  ILogger<AbCipAlarmProjection> (default NullLogger) and log around
  every read / write / template-fetch / probe / alarm-poll failure path.
- Driver.AbCip-011: LogWarning when InitializeAsync is configured with
  Probe.Enabled=true but ProbeTagPath is blank — operators now see why
  GetHostStatuses keeps reporting Unknown.
- Driver.AbCip-012: documented the LibplctagTemplateReader per-call
  Tag cost as accepted given libplctag's own connection pool and the
  low-frequency discovery use-case.
- Driver.AbCip-013: per-device AllowPacking + ConnectionSize overrides
  on AbCipDeviceOptions, threaded through AbCipTagCreateParams; central
  BuildCreateParams helper replaces five ad-hoc clones; AllowPacking
  now reaches Tag.AllowPacking at runtime.
- Driver.AbCip-015: stale-comment sweep — every PR-N forward-reference
  is rewritten to describe present behaviour.
