fix: replace hardcoded response messages with localized strings

- Replace hardcoded 'OK' messages in monitorController with proper localized strings
- Add new string constants to en.json for consistent messaging
- Follow existing pattern used by other controller methods
- Resolves TODO comment in getMonitorsAndSummaryByTeamId method

Fixes: Hardcoded response messages inconsistent with i18n architecture
