apollo_mempool: rename get_timestamp functions

[ayeletstarkware]

Note

Medium Risk
Medium risk: changes touch consensus vote handling and stream buffering/eviction logic, plus batcher proposal-finalization and L1 event plumbing, which could affect liveness if edge cases are missed. CI workflow gating was also removed, potentially increasing PR load and changing when benchmarks run.

Overview
This PR replaces apollo_l1_provider usage with a new apollo_l1_events provider across the workspace (new crates added, dependencies updated, and nextest serialized filters switched), and updates batcher metrics/error types accordingly.

It refactors batcher proposal validation finalization by removing Finish/Abort from SendProposalContent and introducing explicit finish_proposal/abort_proposal requests/responses (FinishProposalStatus), plus renames timestamp retrieval to get_batch_timestamp backed by mempool’s resolve_batch_timestamp.

On the consensus side, it deduplicates cached future votes and reports peers on equivocation, and reworks the stream handler’s inbound LRU from a single (peer, stream) cache to a two-level per-peer cache with new eviction behavior and tests. Separately, storage reader server spawning is updated to use the new spawn() API and always keep an abort handle alive.

CI workflows drop the Graphite optimize_ci job and related skip conditions, causing jobs (including benchmarks) to run unconditionally when their existing event/title guards allow.
