Evm node (threshold encryption sequencer): Catch-up logic when Evm node reconnects
Depends on !13191 (merged)
If the node goes down but the DSN sidecar remains operational, there is a scenario where the EVM node sends a proposal but does not receive the blueprint. Right now, this is not a problem since the EVM node will send a new proposal with the same blueprint number of the previous one, but this approach won't scale when the invariant that preblocks are generated only by sequencer proposals will be broken (i.e. if we ever go into full-blown consensus).
The EVM Node should have a catch-up mechanism, where upon start-up it requests all the blueprints it does not know about to the dsn sidecar.
