Improved observability for stellar-tfchain bridge

[sameh-farouk]

We require improved observability for our bridges. This can be achieved by implementing a REST endpoint that provides health metrics or by enabling the services to output structured logs/events that help monitor real-time abnormalities and evaluate system health.

To achieve better observability into the bridges, we need to expose data such as bridge wallet balances and processed height in both chains.

Update:

As we talked with @sameh-farouk on last meeting, we are waiting for feed back and validation for TFChain <=> Stellar bridge logging (which is already live) to replicate the same patterns and adapt it to Stellar <=> EVM bridge.
