[Cashtab] [Alias] pt 6.1.1 - Apply Promise.All approach for alias history retrieval

Summary:
T2551

Depends on D13018

Applying the Promise.All approach from https://reviews.bitcoinabc.org/D13018 for retrieving the full tx history from the alias payment address across the following functions:

• isAliasAvailable() - updated to use getAllTxHistory() instead of getAliasPaymentHistory()
• getAliasPaymentHistory() - function removed now that getAllTxHistory() retrieves the full history
• getAliases() - adjusted parsing logic to reflect the updated JSON response from getAllTxHistory() (txs object array is now at the top level)

No changes needed for isAliasRegistered() & getAddressFromAlias() as they didn't reference any JSON params.
