Unify `DataStorage`

**Summary**
Currently we've only one `DataStorage` for Wallet Connect but we can save all data instances via one `DataStorage`.

**Suggested features or ways to address the summary**
- We can have storable instances as and injectable `IStorable` with a `StoragePath` and `LoadOnInitialize` properties that can be used to save/load data on Web3 initialize.
- We can have `DataStorage` as an injectable service that can save/load data.

**Motivation**
- This will help us easily save and load data by just extending `IStorable`, will increase reusability, maintainability and readability of the codebase.

**Acceptance Criteria**
- Instances can be saved and loaded just by extending `IStorable`
- `DataStorage` will be responsible for saving, loading, deleting and resetting data
