Subject: [PATCH] fix(frontend): fix i18n and runtime error in EndpointList

Fix hardcoded English labels in cache strategy display and prevent runtime
error when filePatterns is undefined.

Changes:
- Replace hardcoded "TTL:", "Max:", "Patterns:" with formatMessage calls
- Add optional chaining for filePatterns.length to prevent undefined error
- Add "filePatterns" i18n key to en/zh api-settings.json
