chore(release): v2.0.6 — bulk plan creation

Assign one project/category to many employees over a date range in one
action. "Hromadné přiřazení" on /plan-work: employee checklist +
include-weekends toggle, mirrors the single-create form. Creates range
entries grouped by contiguous eligible days per employee (weekends-off →
per-work-week chunks); per-day cap skips days already at 3; 92-day range
cap. Reuses createEntry; summary audit + result counts. No migration.
