feat(telemetry/relayer): improve monitoring of persistent packet data query failures

[GarmashAlex]

Closes: #4298

Description

This PR improves the monitoring of persistent packet data query failures in Hermes.
The following changes were made:
crates/telemetry/src/state.rs:

• Added a new metric (persistent_packet_data_query_failures) to track repeated or persistent failures when querying packet data for relaying. This helps distinguish between transient and long-standing issues.
  crates/relayer/src/link/packet_events.rs:
• Integrated the new metric, incrementing it whenever a chunk of packet sequences fails to return any events (i.e., persistent missing packet data).
  crates/relayer/src/link/relay_path.rs:
• Refactored to propagate telemetry_state into packet event query functions, enabling the new metric to be updated in relevant code paths.

Most critical files to review:

• crates/telemetry/src/state.rs
• crates/relayer/src/link/packet_events.rs
• crates/relayer/src/link/relay_path.rs
