Subject: [PATCH] mode: add L1-fork aliases (cancunTime=ecotoneTime,
 pragueTime=isthmusTime, osakaTime=karstTime) to fix geth init validation

Fixes OP-Stack invalidity error: CancunTime (<nil>) must equal EcotoneTime (1710374401)
Required by op-geth chain config validation which enforces:
- CancunTime == EcotoneTime (1710374401)
- PragueTime == IsthmusTime (1746806401)
- OsakaTime == KarstTime (1783526401)
