`POST /api/v1/contracts/call` returns HTTP 500 for gas estimation when sender is ECDSA-keyed and `value > 0`

## Description

On a `POST /api/v1/contracts/call` request with `"estimate": true`, the web3 module returns
HTTP 500 (`Internal Server Error`) when **both** of the following are true:

- `from` is an ECDSA (secp256k1) account, and
- `value` is greater than 0.

The same request returns HTTP 200 when `value` is omitted, or when `from` is an ED25519 account.

Expected: the request returns an HTTP 200 gas estimate (as it does for the ED25519 sender and the
no-value cases).

Observed on mirror node `v0.156.0` (web3 module), deployed via solo against consensus node
`v0.73.0`.

## Steps to reproduce

1. Deploy a local network with solo (consensus node `v0.73.0`, mirror node `v0.156.0`):

   ```bash
   cat > /tmp/mirror-node-values.yaml <<'EOF'
   web3:
     env:
       HIERO_MIRROR_WEB3_OPCODE_TRACER_ENABLED: "true"
       HIERO_MIRROR_WEB3_EVM_NETWORK: "OTHER"
   EOF

   cat > /tmp/falcon-local.yml <<EOF
   network:
     --release-tag: "v0.73.0"
     --node-aliases: "node1"
   setup:
     --release-tag: "v0.73.0"
     --node-aliases: "node1"
   consensusNode:
     --node-aliases: "node1"
   mirrorNode:
     --enable-ingress: true
     --pinger: true
     --mirror-node-version: "v0.156.0"
     --values-file: "/tmp/mirror-node-values.yaml"
   EOF

   npx @hashgraph/solo@0.78.0 one-shot falcon deploy \
     --values-file /tmp/falcon-local.yml \
     --dev --deploy-explorer=false --deploy-relay=false
   ```

   The deploy output prints funded accounts. Note one `0.0.100x` account address (these are
   ECDSA / hex private key), e.g. `0.0.1003`.

2. Port-forward the web3 module:

   ```bash
   kubectl port-forward -n one-shot svc/mirror-1-web3 8545:80
   ```

3. Send the gas-estimation call with an ECDSA `from` and `value > 0` (replace `EC` with the
   account from step 1):

   ```bash
   EC=0x05fba803be258049a27b820088bab1cad2058871
   URL=http://127.0.0.1:8545/api/v1/contracts/call

   curl -s -w '\nHTTP %{http_code}\n' -X POST "$URL" -H 'Content-Type: application/json' \
     -d "{\"from\":\"$EC\",\"to\":\"0x742d35Cc6634C0532925a3b844Bc454e4438f44e\",\"value\":5000000000,\"estimate\":true}"
   ```

   Result: HTTP 500, body `{"_status":{"messages":[{"message":"Internal Server Error","detail":"","data":""}]}}`.

4. For comparison, the same call without `value` returns HTTP 200:

   ```bash
   curl -s -w '\nHTTP %{http_code}\n' -X POST "$URL" -H 'Content-Type: application/json' \
     -d "{\"from\":\"$EC\",\"to\":\"0x742d35Cc6634C0532925a3b844Bc454e4438f44e\",\"estimate\":true}"
   ```

5. And the same call with an ED25519 `from` (treasury `0.0.2`) and `value > 0` returns HTTP 200:

   ```bash
   curl -s -w '\nHTTP %{http_code}\n' -X POST "$URL" -H 'Content-Type: application/json' \
     -d '{"from":"0x0000000000000000000000000000000000000002","to":"0x742d35Cc6634C0532925a3b844Bc454e4438f44e","value":5000000000,"estimate":true}'
   ```

### Observed results

| `from` key type        | `value`  | HTTP status |
| ---------------------- | -------- | ----------- |
| ECDSA                  | none / 0 | 200         |
| ECDSA                  | > 0      | 500         |
| ED25519 (treasury 0.2) | > 0      | 200         |

## Additional context

When the 500 occurs, the `mirror-1-web3` pod logs the following:

```
kubectl logs -n one-shot deploy/mirror-1-web3
```
