Adds ~40 automation.ruleEditor.* and automation.workflowEditor.* keys
to en.ts + zh.ts (labels, placeholders, error messages, action labels).
RuleFormModal and WorkflowFormModal now route every hardcoded English
string through useT(), including validation errors and modal titles.
Closes remaining Z-B i18n work after the prompt-builder locale
dispatch (cf92e0c), dept-keywords typing (a78bdb9), and sidebar/
formatters/notification/skills i18n landed earlier.
