feat(mix): cover traffic with constant rate
- Integrate ConstantRateCoverTraffic from libp2p mix module with default
  totalSlots = userMessageLimit (or 2) and 10s epoch
- Add --mix-user-message-limit and --mix-disable-spam-protection CLI flags
  with corresponding MixConfBuilder accessors and MixConf fields
- Wrap mixRlnSpamProtection construction so it is skipped when spam
  protection is disabled, with a nil guard in setupSpamProtectionCallbacks
- Add waku/common/option_shims.nim restoring valueOr/withValue templates
  for std/options (removed upstream by results), and import it across
  modules that relied on the old behavior
- Sink chat2mix logs to textlines (stdout) instead of textlines[file] to
  work around a chronicles compile-time macro-eval bug under Nim 2.2.4
- Rename ExtendedKademliaDiscoveryParams -> ExtendedServiceDiscoveryParams
  to match the kad_disco -> service_discovery rename in nim-libp2p
- Bump nim-libp2p to e1bbda4f6 (PR #2243 "cover traffic with constant
  rate") and mix-rln-spam-protection-plugin to 153d0c0 (PR #5 cover
  traffic epoch change support); both pre-libp2p_mix-extraction
- Add simulations/mixnet/check_cover_traffic.sh for monitoring
  mix_cover_* / mix_slot_* metrics, plus per-node cover-traffic configs
