fix(chainselection): prevent overflow in catch-up 2*K calculation

Use safeAddUint64(K, K) instead of 2*K to prevent uint64 overflow
when securityParam is large.

fix(chainselection): relax implausible tip check during catch-up

After a stall, recorded peer tips go stale while the network advances.
When a known peer's tip jumps by >K blocks (Case 1) or a new peer's
tip exceeds best_peer + K (Case 2), the check rejects the tip as
implausible. This creates a deadlock: the node can never advance
because it rejects all peers that have the blocks it needs.

Add a catch-up relaxation: when the reference block is at or behind
the local tip (indicating stale peer records), widen the acceptance
window to 2*K of the local tip. This breaks the deadlock while still
rejecting spoofed tips when the node is healthy (reference > local
tip means peer records are current).
