rename: Etna → Quasar Edition

Wire-level renames in EVM:
  - extras.NetworkUpgrades.EtnaTimestamp → QuasarTimestamp
    json tag etnaTimestamp → quasarTimestamp
  - extras.NetworkUpgrades.IsEtna()      → IsQuasar()
  - extras.LuxRules.IsEtna               → IsQuasar
  - params.RulesExtra.IsEtna             → IsQuasar
  - extras.TestEtnaChainConfig           → TestQuasarChainConfig
  - params.TestEtnaChainConfig           → TestQuasarChainConfig
  - upgradetest.Etna fork enum           → Quasar (luxfi/upgrade dep)

Test JSON fixtures (mainnet_upgrade_v46, testnet_upgrade_v47, embedded
genesis_skippostmerge_test, precompile_upgrade_rollout_test) flipped from
"etnaTimestamp" → "quasarTimestamp".

Also patched .disabled test files for grep cleanliness so future grep -rn
'Etna' returns 0 outside historical RELEASES.md.

Bumps luxfi/upgrade@main + luxfi/constants@main with their renamed symbols.
No backcompat aliases — forwards-only.
