fix: unify theme system - fix theme switching persistence

- Unified localStorage key to 'theme-preference' across all components
- Fixed header.tsx using wrong localStorage key ('theme' instead of 'theme-preference')
- Added localStorage hybrid persistence for instant theme changes
- Removed router.refresh() which was causing stale data revert
- Replaced Blue theme with Sepia
- Consolidated auth() calls to prevent race conditions
- Updated UserSettingsData types to include all themes

+### Change Log
+
+**2026-01-17 - Auto-Labeling Bug Fix Implementation**
+
+**Problem:**
+Auto-labeling feature was not working when creating new notes. The `contextualAutoTagService` existed but was never called during note creation, resulting in notes being created without any automatic labels.
+
+**Root Cause:**
+The `createNote()` function in `keep-notes/app/actions/notes.ts` did not integrate the auto-labeling service. It only used labels if they were explicitly provided in the `data.labels` parameter.
+
+**Solution:**
+1. Added import of `contextualAutoTagService` from AI services
+2. Added `getConfigBoolean` import from config utilities
+3. Integrated auto-labeling logic into `createNote()`:
+   - Checks if labels are provided
+   - If no labels and note has a notebookId, calls `contextualAutoTagService.suggestLabels()`
+   - Applies suggestions that meet the confidence threshold (configurable via AUTO_LABELING_CONFIDENCE_THRESHOLD)
+   - Auto-labeling can be disabled via AUTO_LABELING_ENABLED config
+   - Graceful error handling: continues with note creation even if auto-labeling fails
+
+**Configuration Added:**
+- `AUTO_LABELING_ENABLED` (default: true) - Enable/disable auto-labeling feature
+- `AUTO_LABELING_CONFIDENCE_THRESHOLD` (default: 70) - Minimum confidence percentage for applying auto-labels
+
+**Testing:**
+- Created comprehensive E2E test suite in `bug-auto-labeling.spec.ts`:
+  - Test auto-labeling for programming-related content
+  - Test auto-labeling for meeting-related content
+  - Test immediate label display without page refresh (critical requirement)
+  - Test graceful error handling when auto-labeling fails
+  - Test auto-labeling in notebook context
+
+**Expected Behavior After Fix:**
+When a user creates a note in a notebook:
+1. System automatically analyzes note content using AI
+2. Relevant labels are suggested based on notebook's existing labels or new suggestions
+3. Labels with confidence >= threshold are automatically assigned
+4. Note displays with labels immediately (no page refresh needed)
+5. If auto-labeling fails, note is still created successfully
