Replace manual types with xrpl.js types

[pdp2121]

Replace manual types with xrpl.js types. For example:

explorer/src/containers/shared/components/Transaction/types.ts

Lines 55 to 70 in f0d7385

	export interface TransactionCommonFields {
	date: string
	Account: string
	TransactionType: string
	Fee: string
	Sequence: number
	AccountTxnID?: string
	Flags?: number
	LastLedgerSequence?: number
	Memos?: Memo[]
	Signers?: object[]
	SourceTag?: number
	SignerPubKey?: string
	TicketSequence?: number
	TxnSignature?: string
	}

should be replaced with BaseTransaction. Similar things applied to fields such as:

explorer/src/containers/shared/components/Transaction/DIDDelete/types.ts

Lines 4 to 6 in f0d7385

	export interface DIDDelete extends BaseTransaction {
	TransactionType: 'DIDDelete'
	}
