Automamatically reload pages after noticeable change

[ismaelsadeeq]

Currently, the pages are static and require a manual refresh to update. The following changes are needed:

1. Dashboard: Should automatically reload when there is a change in the node's fee rate estimate, a new block confirmation, or a chain reorganization (reorg).

2. Stats Page: Should reload automatically whenever new data points are recorded.

3. Mempool Page: Should reload after any significant change in the mempool.
