feat(fusion_clock): schedule-driven attendance automation

Reminders, absence detection, late/early penalties, and auto-clock-out are now
driven by each employee's real schedule (posted planner entry -> recurring
shift), never the global 9-5 default. Employees who aren't scheduled get no
reminders/absence. Overtime past the scheduled end is never cut off — auto
clock-out only fires at a max-shift safety cap (default raised 12 -> 16h). Team
leads build the planner in draft and Post it (publishes + emails employees).

- hr.employee._get_fclk_day_plan: explicit `scheduled` flag; posted-only planner
  entries (drafts ignored), else recurring shift covering that weekday, else
  not-scheduled; sources 'schedule'/'shift'/'none'.
- fusion.clock.shift: day_mon..day_sun weekday pattern + covers_weekday().
- fusion.clock.schedule: draft/posted state + posted_date; planner edits reset
  to draft; fclk_email_posted_week notification.
- Rewrote the reminder / absence / auto-clock-out crons: schedule-gated,
  per-employee savepoints, OT-aware cap, weekend hardcode removed.
- Penalties + all three clock-in paths skip days the employee isn't scheduled.
- shift_planner: Post Week route + planner Post button + draft count.
- Migration backfills pre-existing schedule entries to 'posted' so they keep
  driving automation after upgrade.
- Tests: resolver matrix, cron gating, OT cap; fixed the existing planner test
  for the new state/source semantics.

Design: docs/superpowers/specs/2026-05-30-schedule-driven-attendance-design.md
Frontend footprint kept at zero to avoid colliding with the concurrent
employee-portal (payslips) work.
