Add a Zagros Asset Hub history indexer for the explorer host

Browse Source 
The explorer at explorer.pezkuwichain.io needs transfer history for Zagros
Asset Hub. It runs on the explorer host next to its own archive node, so the
manifest points at 127.0.0.1:9955 and the compose file binds everything
locally with memory limits and no published ports.

deploy-vps now ignores these files: a change to the Zagros indexer must not
rebuild or restart the mainnet stack and its bots on the indexer host.

# Zagros Asset Hub history (explorer host)
Serves `HistoryElement` for Zagros Asset Hub to explorer.pezkuwichain.io. It
runs on the explorer host next to its own archive node, never on the mainnet
indexer host (`deploy-vps` ignores `zagros-assethub.yaml`,
`docker-compose.zagros.yml` and this directory).
## Pieces
| piece | where | listens |
|---|---|---|
| archive node `zagros-ah-archive` (systemd, `--state-pruning archive --blocks-pruning archive`, relay followed over RPC) | host | RPC 127.0.0.1:9955 |
| postgres 16 | compose | 127.0.0.1:5433 |
| subql-node, `zagros-assethub.yaml` | compose | 3101 (firewalled) |
| subql-query | compose | 3100 (firewalled); nginx exposes `POST /history/assethub` only |
## Build and start
```sh
git clone https://github.com/pezkuwichain/pezkuwi-subquery /opt/zagros-history
cd /opt/zagros-history
# Build the mapping (dist/) without installing Node on the host.
docker run --rm -v "$PWD":/w -w /w node:24-alpine sh -c \
'corepack enable && yarn install --immutable && yarn subql codegen zagros-assethub.yaml && yarn subql build zagros-assethub.yaml'
printf 'ZAGROS_DB_PASS=%s\n' "$(openssl rand -hex 24)" > .env.zagros && chmod 600 .env.zagros
docker compose -f docker-compose.zagros.yml --env-file .env.zagros up -d --build
```
## Check
```sh
curl -s -X POST 127.0.0.1:3100 -H 'content-type: application/json' \
-d '{"query":"{_metadata{lastProcessedHeight targetHeight}}"}'
```
`targetHeight - lastProcessedHeight` above 100 for ten minutes means the
indexer has stalled; the explorer then shows "on its way" for payments it has
not seen yet.
