feat: initial hive -> SQLite (#2502)

* feat: initial hive -> SQLite

Includes migration script and initial work done to
remove dependency on hive generators.

Also contains some refactoring to make sync code
async.

Features new dev screen that lists all SQLite tables

Aspects that need testing:
- backups (from this version, and from previous versions as well)
- wallet loading / wallet list
- almost everything else
- renaming
- deletion
- sorting in wallet list
- wallet groups
- wallet seed/keys
- wallet switching
- wallet creation / restore - all methods
- wallet address page
- hardware wallet connection (and prompts from mall screens)
- contacts
- advanced settings in wallet creation
- derivation paths
- some minor wownero fixes
- base, hardware wallets

* fix: build errors

* fix: Bad state: No element in backup restore

* address comments from review

* fix: HardwareWalletType
