Two related fixes for running the explorer against a mainnet-fork
devnet:
1. Honor the per-chain `indexer.start_block` field from chains.yaml
when the indexer DB is fresh. Without this the indexer always
backfills from block 0, which on a mainnet fork is 25M+ blocks of
irrelevant pre-fork history. Now an operator can set:
chains:
- slug: evm
rpc: http://anvil:8545
indexer:
start_block: 25162000
and the indexer skips to that block on first run. Once any rows
exist in evm_blocks, start_block is ignored and indexing resumes
from MAX(number)+1 as before — backward-compatible for
fresh-genesis chains.
2. Default the bundled SPA's NETWORK_ID to 8675312 (the Liquid
devnet chain ID). The Dockerfile previously inherited
luxfi/explore's default of 8675311 — a stale leftover from before
the devnet chainId migration. Adds NETWORK_ID / NETWORK_NAME /
CURRENCY_SYMBOL as build-args so the same Dockerfile produces
correct images for devnet/testnet/mainnet.
Requires luxfi/indexer #8 (StartBlock field on evm.Config) — bumped
via `go mod edit` to the post-merge commit d5e65d4b50c1.
