feat: implement new dashboard widgets and features including Gauge, Table, and enhanced chart capabilities

Internal/Roadmap/Dashboards.md

@@ -19,23 +19,33 @@ The following features have been implemented:
 - **Role-Based Permissions** - ProjectOwner, ProjectAdmin, ProjectMember + custom permissions
 - **Dashboard CRUD API** - Standard REST API with slug generation
 - **Billing Enforcement** - Free plan limited to 1 dashboard
+- **Area Chart** (Phase 1.1) - Area and Stacked Area chart types added to ChartType enum and rendered via chart component
+- **Table Widget** (Phase 1.1) - New DashboardComponentType.Table with timestamp/value columns, sticky header, configurable max rows
+- **Gauge Widget** (Phase 1.1) - SVG semi-circle gauge with threshold-based color coding (green/yellow/red), configurable min/max/thresholds
+- **Template Variables** (Phase 1.2) - DashboardVariable type with CustomList, Query, and TextInput types; toolbar dropdown/input selectors; variable changes trigger widget refresh
+- **Auto-Refresh** (Phase 1.3) - 7 interval options (5s to 15m), timer pauses in edit mode, pulsing indicator, interval persisted in dashboard config
+- **Multiple Queries per Chart** (Phase 1.4) - metricQueryConfigs array support with fallback to single metricQueryConfig; each query rendered as a separate series
+- **Markdown Support** (Phase 1.5) - isMarkdown flag on text components; renders LazyMarkdownViewer when enabled, falls back to bold/italic/underline when disabled
+- **Threshold / Color Coding** (Phase 1.6) - Warning and critical threshold config on Value and Chart components; Value widget changes background/text color (green → yellow → red) based on thresholds
+- **Legend Interaction** (Phase 1.7) - onValueChange enabled on Line, Area, and Bar charts for built-in Tremor legend click-to-toggle filtering
+- **Chart Zoom** (Phase 1.8) - Time range zoom stack with Reset Zoom button in toolbar; pushing current range before zoom, popping on reset
