tac: add TAC mainnet archive profile with EVM JSON-RPC upstream

Browse Source 
- Add archive profile (pruning=nothing) for tacchaind
- Change client_rpc_port from 26657 (CometBFT) to 8545 (EVM JSON-RPC)
- Update Dockerfile to download pre-built binary from GitHub releases v1.6.0
- Verify binary against checksums.txt
- Update init.sh to support PRUNING env var (nothing for archive, default for pruned)
- Update peers from NETWORKS.md
- Add archive snapshot URL note
- Traefik routes to EVM JSON-RPC port 8545 for both pruned and archive
