Fix WebSocket events being silently dropped on buffer overflow (#313)

* Fix WebSocket events being silently dropped on buffer overflow

Increases the MutableSharedFlow `extraBufferCapacity` from 64 to 256
and changes the `onBufferOverflow` policy to `BufferOverflow.DROP_OLDEST`
in `HermesWsClient.kt`. This fixes an issue where the slow collection
(e.g., due to DB writes) caused the buffer to fill up and silently drop
incoming real-time WebSocket events.

By setting `DROP_OLDEST`, `tryEmit()` remains functional without
suspending, allowing real-time events to be retained and prioritized.

Fixes #275

* Fix ktlint formatting issues in HermesWsClient.kt

The formatting changes adhere to ktlint rules required by the CI pipeline:
- Removed a trailing comma in MutableSharedFlow initialization to avoid multiline expression wrapping errors.
- Sorted imports to be in lexicographical order.

These formatting changes fix the failing CI check.
