Add device management and database-backed desktop settings

This update migrates desktop grid settings from localStorage to the database
and introduces a comprehensive device management system.

Features:
- New haex_devices table for device identification and naming
- Device-specific settings with foreign key relationships
- Preset-based icon sizes (Small, Medium, Large, Extra Large)
- Grid positioning improvements to prevent dragging behind PageHeader
- Dynamic icon sizing based on database settings

Database Changes:
- Created haex_devices table with deviceId (UUID) and name columns
- Modified haex_settings to include device_id FK and updated unique constraint
- Migration 0002_loose_quasimodo.sql for schema changes

Technical Improvements:
- Replaced arbitrary icon size slider (60-200px) with preset system
- Icons use actual measured dimensions for proper grid centering
- Settings sync on vault mount for cross-device consistency
- Proper bounds checking during icon drag operations

Bump version to 0.1.7
