feat(management): add command to initialize chart data

Introduced a new management command to initialize the database with current data for specified cryptocurrencies (`xmr`, `btc`, `dash`, `zec`, `grin`). This process involves deleting existing data entries and fetching updated historical and market data. This enhancement ensures the application starts with the most recent information, improving data accuracy and reliability.
