Fix Ambiguous ‘rowid’ Column in Web Hooks List Query Count

### PR Description:
This pull request addresses an issue where the **Web Hooks List** in Dolibarr was incorrectly showing 0 processed hooks due to an SQL error caused by ambiguity in the `rowid` column during sorting.

The error in the log:
```
2024-10-02 15:59:34 DEBUG   197.15.130.128  3759257   1001 sql=SELECT COUNT(*) AS nb  FROM llx_ecommerce_pending_webhooks AS epw LEFT JOIN llx_ecommerce_site AS es on es.rowid = epw.site_id WHERE es.entity IN (1) ORDER BY epw.status ASC, rowid ASC
2024-10-02 15:59:34 ERR     197.15.130.128  3759257   1001 DoliDBMysqli::query Exception in query instead of returning an error: Column 'rowid' in order clause is ambiguous
2024-10-02 15:59:34 ERR     197.15.130.128  3759257   1001 DoliDBMysqli::query SQL Error message: DB_ERROR_1052 Column 'rowid' in order clause is ambiguous From /hidden-path/htdocs/custom/ecommerceng/webhookslist.php:240.
```

The fix resolves this ambiguity by specifying the correct table for the `rowid` column in the query. As a result, the **Web Hooks List** now correctly displays the number of hooks instead of showing 0.
