refactor: entity selector full overhaul — Mar 2026

- Unified _setBadgeCount for ALL badge updates
- target-conditions-trait → entity-selector-trait
- target-* → es-* class rename (20+ classes)
- SCSS recompiled: zero duplicate selectors
- CSS transitions replace jQuery slideDown/slideUp
- Serialize cache, method swap cache
- Badge: no-matches gray, consistent hover, no blending
- Inline condition count always visible
- Preview popover refreshes in-place on sort change
- Categories add chips immediately
- Entity type icons on chips
- Consistent info_outline icons via buildHelpIcon
- Method dropdown text clipping fix (line-height)
- mpr-input-compact on all inputs
- Dropdown padding fixed in SCSS source
- Chips wrapper: same container always
- Reusable helpers: _buildEmptyState, _buildSearchBoxHtml, _buildInfoTooltip
- Asset path: uses $this->module->getPathUri() not reflection
- Debug logs removed
