feat: add parityCheckStatus field to array query (#1611)

Responds with a ParityCheck:
```ts
type ParityCheck {
  """Date of the parity check"""
  date: DateTime

  """Duration of the parity check in seconds"""
  duration: Int

  """Speed of the parity check, in MB/s"""
  speed: String

  """Status of the parity check"""
  status: ParityCheckStatus!

  """Number of errors during the parity check"""
  errors: Int

  """Progress percentage of the parity check"""
  progress: Int

  """Whether corrections are being written to parity"""
  correcting: Boolean

  """Whether the parity check is paused"""
  paused: Boolean

  """Whether the parity check is running"""
  running: Boolean
}

enum ParityCheckStatus {
    NEVER_RUN = 'never_run',
    RUNNING = 'running',
    PAUSED = 'paused',
    COMPLETED = 'completed',
    CANCELLED = 'cancelled',
    FAILED = 'failed',
}
```

## Summary by CodeRabbit

- New Features
- Exposes a structured parity-check status for arrays with detailed
fields (status enum: NEVER_RUN, RUNNING, PAUSED, COMPLETED, CANCELLED,
FAILED), date, duration, speed, progress, errors, and running/paused
flags.

- Tests
- Adds comprehensive unit tests covering all parity-check states,
numeric edge cases, speed/date/duration/progress calculations, and
real-world scenarios.

- Refactor
- Safer numeric/date parsing and a new numeric-conversion helper; minor
formatting/cleanup in shared utilities.
