feat: better self-rate-limit handling

[wemeetagain]

Motivation

• Builds on feat(reqresp): track peer rate-limit backoff in SelfRateLimiter #9034

Description

• track rate limits per-peer, per-protocol on the reqresp layer (note that in range and unknown block sync the rate limit is still just per-peer for simplicity)
• include rate-limit timestamp in rate limit errors (use this in range and unknown block sync for backoff time)
• use rate limit in unknown block sync (see this comment: feat(reqresp): track peer rate-limit backoff in SelfRateLimiter #9034 (comment))
• add a timer in range and unknown block sync to trigger another download attempt after backoff time (handles the case where all peers are rate-limited and the sync needs a wake-up)

Code Review

This pull request introduces a protocol-aware rate-limiting backoff mechanism for unknown block synchronization. It adds the UnknownBlockRateLimitedError class and updates BlockInputSync to handle retries using specific backoff timestamps. Additionally, SelfRateLimiter and UnknownBlockPeerBalancer were refactored to track and respect these limits per peer and protocol. Feedback suggests refactoring getNextRateLimitRetryAt to separate cleanup side effects from the query logic for better maintainability.
