fix platform services to use correct settings table schema

- Fix WebPlatformService settings methods to use id/accountDid columns
- Fix CapacitorPlatformService settings methods to use id/accountDid columns
- Replace WHERE key = 'default' with WHERE id = 1 for default settings
- Replace WHERE key = ? with WHERE accountDid = ? for user settings
- Update insertDidSpecificSettings to use accountDid column
- Update retrieveSettingsForActiveAccount to select all columns and convert to object
- Resolves "no such column: key" SQL errors after util.ts migration
- Ensures compatibility with new settings table structure

All platform services now use correct database schema for settings operations.
