fix: Match HiBob API field names for timeoff display (#6)

## Summary
- Add `employeeDisplayName` and `policyTypeDisplayName` to field
extractors — the actual field names returned by the HiBob API — fixing
"Unknown" names and missing type labels in `outtoday`/`whosout` output
- Add a count header ("N people out") and remove redundant email column
from text output
- Include the actual API field names in `TIMEOFF_ESSENTIAL_FIELDS` for
JSON/NDJSON output

## Test plan
- [x] `bob outtoday` shows real names and type labels instead of
"Unknown"
- [x] `bob whosout --from ... --to ...` same
- [x] `bob outtoday --json` includes `employeeDisplayName`,
`policyTypeDisplayName`, `employeeEmail`
- [x] `bob outtoday --ndjson` same
- [x] Pre-commit hooks pass (biome lint + type-check)
