fix(docker): improve channel setup timing for clean slate

- Add is_lnd1_wallet_ready() to verify wallet is ready before operations
- Mine initial blocks if blockchain has < 101 blocks (fresh regtest)
- Wait for lnd-1 to sync to chain before opening channels
- Create bitcoind wallet if needed (clean slate)
- Increase channel activation wait from 40s to 60s
- Add explicit graph propagation check via queryroutes
- Wait up to 60s for lnd-3 to find route to lnd-4 before funding

This ensures the environment works from a completely clean Docker
slate without relying on the scheduled miner.
