fix: move VWAP bootstrap from forge script to bootstrap-common.sh

Browse source 
vm.warp in forge script --broadcast only affects the local simulation
phase, not the actual Anvil node.  The pool.observe([300,0]) call in
recenter() therefore reverted with OLD when Forge pre-flighted the
broadcast transactions on Anvil.

Fix:
- Remove the vm.warp + 2-recenter + SeedSwapper VWAP bootstrap from
  DeployLocal.sol (only contract deployment now, simpler and reliable).
- Add bootstrap_vwap() to bootstrap-common.sh that uses Anvil RPC
  evm_increaseTime + evm_mine to advance chain time before each recenter,
  then executes a 0.5 ETH WETH->KRK seed swap between them.
- Call bootstrap_vwap() before fund_liquidity_manager() in both
  containers/bootstrap.sh and ci-bootstrap.sh so the LM is seeded with
  thin positions (1 ETH) during bootstrap, ensuring the 0.5 ETH swap
  moves the price >400 ticks (amplitude gate).
