Management server hangs when js.interpretation.enabled=true

### problem

Enabling the global setting `js.interpretation.enabled=true` causes the CloudStack management server to hang during startup at the module loading phase. This prevents using the secondary storage selector feature (`createSecondaryStorageSelector`, `updateSecondaryStorageSelector` APIs).

### versions

- 4.20 branch (4.20.3.0-SNAPSHOT) - **AFFECTED** - needs fix before 4.20.3.0 release
- 4.20.2.0 (released) - Not affected (commit not present, setting does not exist, APIs work unconditionally)

Introduced by commit `03a4b9f` ("server,utils: improve js interpretation functionality") merged on Oct 16, 2025 into the 4.20 branch.

The commit:
1. Added `js.interpretation.enabled` as a hidden ConfigKey (default: false)
2. Made `CreateSecondaryStorageSelectorCmd` and `UpdateSecondaryStorageSelectorCmd` conditional on this setting
3. Made significant changes to `JsInterpreter.java` (security hardening, daemon workers, etc.)

When the setting is enabled, something in the initialization causes the MS server to hang.

### The steps to reproduce the bug

1. Deploy CloudStack 4.20.3.0
2. Verify server is running:
```
curl -s "http://localhost:8080/client/api?command=listZones" | head -5
```
3. Enable the js.interpretation.enabled setting:
```
mysql -u root -p cloud -e "UPDATE configuration SET value='true' WHERE name='js.interpretation.enabled';"
```
4. Restart management server:
```
systemctl restart cloudstack-management
```
5. Wait 3+ minutes and check server status:
```
curl -s "http://localhost:8080/client/api?command=listZones" | head -5
```

### Expected Result
Server starts successfully and `createSecondaryStorageSelector` API is available.

### Actual Result
Server returns 503 Service Unavailable. Log shows server stuck at module loading phase:
```
2026-01-26 19:53:01,937 DEBUG [o.a.c.s.m.m.i.DefaultModuleDefinitionSet] (main:[]) (logid:) Trying to obtain module [redfish] context.

```

Log timestamp remains static while current time progresses - server is hung.

#### Evidence

**4.20 branch build (shapeblue18197) - Bug present:**
```
[root@ref-trl-10730-k-Mol9-rositsa-kyuchukova-mgmt1 ~]# rpm -qa | grep cloudstack
cloudstack-common-4.20.3.0-shapeblue18197.noarch
cloudstack-management-4.20.3.0-shapeblue18197.noarch

[root@ref-trl-10730-k-Mol9-rositsa-kyuchukova-mgmt1 ~]# mysql -u root -p cloud -e "UPDATE configuration SET value='true' WHERE name='js.interpretation.enabled';"
[root@ref-trl-10730-k-Mol9-rositsa-kyuchukova-mgmt1 ~]# systemctl restart cloudstack-management
[root@ref-trl-10730-k-Mol9-rositsa-kyuchukova-mgmt1 ~]# sleep 180
[root@ref-trl-10730-k-Mol9-rositsa-kyuchukova-mgmt1 ~]# curl -s "http://localhost:8080/client/api?command=listZones" | head -5

Error 503 Service Unavailable

```

**4.20.2.0 released version (shapeblue17631) - Works correctly:**
```
[root@ref-trl-10714-k-Mol9-rositsa-kyuchukova-mgmt1 ~]# rpm -qa | grep cloudstack
cloudstack-common-4.20.2.0-shapeblue17631.noarch
cloudstack-management-4.20.2.0-shapeblue17631.noarch

mysql> SELECT name, value FROM configuration WHERE name LIKE '%interpret%';
Empty set (0.00 sec)

[root@ref-trl-10714-k-Mol9-rositsa-kyuchukova-mgmt1 ~]# cmk list apis 2>/dev/null | grep -i "name.*selector"
"name": "createSecondaryStorageSelector",
"name": "updateSecondaryStorageSelector",
"name": "listSecondaryStorageSelectors",
"name": "removeSecondaryStorageSelector",
```

#### Impact
- Secondary storage selector feature is unusable on current 4.20 branch
- Quota tariff activation rules may also be affected (uses same JsInterpreter)
- Blocks testing of PR #10957 and any other functionality that depends on this feature

### What to do about it?

_No response_

Reproduza o travamento na inicialização com js.interpretation.enabled=true e inspecione os logs do management-server em torno de DefaultModuleDefinitionSet. Leia JsInterpreter.java e as alterações do commit 03a4b9f, incluindo CreateSecondaryStorageSelectorCmd e UpdateSecondaryStorageSelectorCmd, verificando também os PRs relacionados. Considera-se concluído quando o management-server iniciar normalmente com a configuração habilitada e as APIs de secondary storage selector estiverem disponíveis.
