fix(driver-focas): resolve Low code-review findings (Driver.FOCAS-007,008,009,010,011)

- Driver.FOCAS-007: optional ILogger<FocasDriver> + alarm-projection
  logger; log Debug around every formerly-empty catch (probe / shutdown
  / fixed-tree / recycle / alarms-read / projection).
- Driver.FOCAS-008: cache the parsed FocasAddress per tag at
  InitializeAsync; Read/WriteAsync look it up instead of re-parsing on
  every call.
- Driver.FOCAS-009: ProbeLoopAsync now wraps client.ProbeAsync in a
  linked CTS honouring Probe.Timeout so a hung CNC socket can't block
  past the configured limit.
- Driver.FOCAS-010: FocasOperationModeExtensions.ToText delegates to
  FocasOpMode.ToText — single canonical op-mode label surface.
- Driver.FOCAS-011: FocasAlarmType constants are typed short to match
  the cnc_rdalmmsg2 wire field and the projection switch arms.
