Add fee stats RPC

[chenyukang]

• fee_report: Returns a summary of forwarding fees earned over day/week/month windows,
  grouped by asset type (CKB and each UDT).

• forwarding_history: Returns individual forwarding events with optional time range, asset filter, and pagination.

Pull request overview

Adds fee/payment statistics and history reporting to the Fiber node by persisting forwarding/payment events and exposing new Info-module JSON-RPC methods (plus WASM + CLI surface updates).

Changes:

• Introduces ForwardingEvent / PaymentEvent data models, new store prefixes, and a ChannelEventStore persistence/query trait with RocksDB implementation and tests.
• Adds Info RPC methods: fee_report, forwarding_history, sent_payment_report, received_payment_report, payment_history, along with JSON types and generated RPC docs.
• Wires new RPCs into authorization (biscuit rules) and the WASM wrapper.
