feat: logs enhancements

[veds-g]

enhanced numaflow logs to:

• added monospacing

• updated logs font, removed colours for log level

• allow wrapping lines (preventing horizontal scroll)

• ability to download logs (format - "{pod_name}-{container_name}.txt")

• ability to add / remove timestamps from the beginning of logs

• add filters for log levels (info, error, warn, debug)
