v0.3.7

Fixed

• Combined sensor: sensor.*_combined_summary attributes now include an entities key (flat list of all monitored entity IDs across all source groups) — required for the Unsuppress All card action to work on combined group cards
• Card: show_actions (Suppress All / Unsuppress All buttons) now rendered for combined group cards; previously the actions block was absent regardless of config
• Card: _getOfflineEntityIds() now uses the combined-group entity prefix when the card is a combined group — Suppress All was silently suppressing nothing on combined cards
