fix(fusion_clock): stop stale missed-clock-in nag; add Owner role + attendance exemption

The "explain your missed clock-out" dialog (driven by hr.employee.
x_fclk_pending_reason) was set by the absence + auto-clock-out crons but only
cleared by the systray reason dialog -- never by the kiosk/NFC clock paths that
staff actually use. During the kiosk rollout the absence cron flagged the whole
company (hundreds of "absent" logs); those stale flags then nagged everyone
forever, even while currently clocked in.

Fixes:
- Clear x_fclk_pending_reason on every successful clock-in (portal, systray,
  PIN kiosk, NFC kiosk). Back on the clock => no nag.
- get_status / dashboard never report pending while checked-in or exempt; the
  systray also guards the dialog client-side.
- Absence detection no longer sets x_fclk_pending_reason (an absence has no
  "departure time" to explain). It still logs 'absent' + notifies the office.
- One-time migration (19.0.4.2.0) clears existing stale flags.

Owner / attendance exemption:
- New "Owner" role (top of the Fusion Clock access dropdown, implies Manager)
  plus a per-employee "Exempt from Attendance" checkbox.
- hr.employee._fclk_is_attendance_exempt(); the absence, auto-clock-out,
  reminder and weekly-summary crons all skip exempt employees, and the dialog
  is suppressed for them.

Tests: tests/test_pending_reason_exempt.py (13 cases). Full fusion_clock suite
green except pre-existing env-sensitive failures.
