Varaverk: Scheduler Information panel with structured how-it-works sections

- Right panel title: "Suggested Schedules" → "Scheduler Information"
- Removed top hint paragraph; info now lives in the panel itself
- Added three collapsible info sections (open by default) at top of panel:
  Controls — toggle, cron, run, dry run, log, stop, verbose, config
  Orchestrators — enabled/disabled behavior, child cron rules, event triggers
  Children & Advanced — toggle semantics, independent cron, rsync flag badge
- Bullet lists use CSS columns:2 with column-fill:balance for even distribution
- "Suggested Schedules" divider separates info from parsed schedule blocks
- Added vvToggleSug() for DOM-traversal-based accordion (no ID dependency)
