Remove refresh icon and fix Safari/WebKit runtime errors

- Removed manual refresh button from frontend (kept auto-refresh functionality)
- Fixed WebKit 'object cannot be found' error by replacing absolute positioning with flexbox
- Added lazy loading to images to prevent preload warnings
- Cleaned up unused imports and variables:
  - Removed unused useRef import
  - Removed unused colors state variable and colorService
  - Removed unused ColorSwatch import from FilamentTableV2
  - Removed unused getModifierIcon function from MaterialBadge
- Updated tests to match current implementation
- Improved layout stability for better cross-browser compatibility
- Removed temporary migration scripts

+# Deployment Guide for Filamenteka
+
+## Important: API Update Required
+
+The production API at api.filamenteka.rs needs to be updated with the latest code changes.
+
+### Changes that need to be deployed:
+
+1. **Database Schema Changes**:
+   - Column renamed from `vakum` to `spulna` 
+   - Column `otvoreno` has been removed
+   - Data types changed from strings to integers for `refill` and `spulna`
+   - Added CHECK constraint: `kolicina = refill + spulna`
+
+2. **API Server Changes**:
+   - Updated `/api/filaments` endpoints to use new column names
+   - Updated data type handling (integers instead of strings)
+   - Added proper quantity calculation
+
+### Deployment Steps:
+
+1. **Update the API server code**:
+   ```bash
+   # On the production server
+   cd /path/to/api
+   git pull origin main
+   npm install
+   ```
+
+2. **Run database migrations**:
+   ```bash
+   # Run the migration to rename columns
+   psql $DATABASE_URL < database/migrations/003_rename_vakum_to_spulna.sql
+   
+   # Run the migration to fix data types
+   psql $DATABASE_URL < database/migrations/004_fix_inventory_data_types.sql
+   
+   # Fix any data inconsistencies
+   psql $DATABASE_URL < database/migrations/fix_quantity_consistency.sql
+   ```
+
+3. **Restart the API server**:
+   ```bash
+   # Restart the service
+   pm2 restart filamenteka-api
+   # or
+   systemctl restart filamenteka-api
+   ```
+
+### Temporary Frontend Compatibility
+
+The frontend has been updated to handle both old and new API response formats, so it will work with both:
+- Old format: `vakum`, `otvoreno` (strings)
+- New format: `spulna` (integer), no `otvoreno` field
+
+Once the API is updated, the compatibility layer can be removed.
+
+### Verification
+
+After deployment, verify:
+1. API returns `spulna` instead of `vakum`
+2. Values are integers, not strings
+3. Quantity calculations are correct (`kolicina = refill + spulna`)
