feat(ucs01-relay): create pfm events st hubble can track outgoing hop packets

[PoisonPhang]

• Add event for PFM hops (expected format below)
• Cleanup existing PFM events
• Remove uses of unwrap relevant to PFM

PFM Hop Event Structure

packet_forward_hop:
  - recv_sequence: <u64>
  - dest_channel: <String>
  - dest_port: <String>
  - sent_sequence: <u64>
  - src_channel: <String>
  - src_port: <String>

Real Example

Osmosis -> Union -> Ethereum
