v1.1.0 — Log clearing, random posts/day, and publishing blocks

v1.1.0: Clear logs, random posts-per-day, weekday/date blocking with auto-reschedule

• Add Clear All Logs button to the Publishing Logs page
• Add random posts-per-day mode (min/max range) as an alternative to a fixed number
• Add blocking of publishing on specific weekdays and/or specific dates
• Posts already scheduled on a date that becomes blocked are automatically
  released and rescheduled onto the next valid day, respecting gap/window rules

Fix minimum gap between posts

• Fix: minimum gap between posts is now enforced across separate schedule generation calls, not just within a single call.
