feat(TransactionHistory): status filter toggle, date range startDate/endDate props, rows link to Stellar Expert

[k-deejah]

Problem

1. TransactionHistory does not support filtering by status (Success/Failed) — the list shows all transactions mixed. A status filter (All / Success / Failed) in the card header would help users find failed transactions quickly.

2. TransactionHistory does not support date range filtering — there is no way to narrow the history to a specific date range. Adding start/end date <Input type="date"> fields would let users export or review activity for a period.

3. TransactionHistory row clicks have no action — clicking a row does nothing. Rows should be linkable to Stellar Expert for the active network.

Solution

1. Add status filter toggle buttons (All / Success / Failed) in the card header, passing the filter to getHistory.
2. Add optional startDate/endDate ISO string props to TransactionHistory; pass them to getHistory when set.
3. Wrap each TxRow in an <a href> pointing to the correct Stellar Expert URL for the transaction hash.

Acceptance Criteria

• Status filter buttons show only matching transactions
• startDate/endDate props filter the API call
• Each row links to the correct Stellar Expert URL
• npm run build passes
