Load menus and actions from database (like Python Odoo)

Replaces all hardcoded Go maps with database-driven loading:

Menus (pkg/server/menus.go):
- Queries ir_ui_menu table joined with ir_model_data for XML IDs
- Builds parent/child tree from parent_id relationships
- Resolves appID by walking up to top-level ancestor
- Parses action references ("ir.actions.act_window,123" format)

Actions (pkg/server/action.go):
- Loads from ir_actions_act_window table by integer ID
- Supports XML ID resolution ("sale.action_quotations_with_onboarding")
  via ir_model_data lookup
- Builds views array from view_mode string dynamically
- Handles nullable DB columns with helper functions

Seed data (pkg/service/db.go):
- seedActions(): 15 actions with XML IDs in ir_model_data
- seedMenus(): 25 menus with parent/child hierarchy and XML IDs
- Both called during database creation

This mirrors Python Odoo's architecture where menus and actions
are database records loaded from XML data files.
