feat: add type filter and claude-only fields to batch controls

Batch controls now distinguish codex vs claude agents:
- Type selector (All/Codex/Claude) filters targets and shows count
- Effort options adapt per type (no 'max' for codex-only)
- Color and Permission batch fields shown when claude agents targeted
- Claude-only fields applied individually per agent via PUT endpoint
