Pull request overview

Adds an “escalation after N minutes” capability for monitors so that, if a monitor remains down long enough, additional notification channels can be alerted. This extends the monitor model (DB + types + validation), updates notification message building, and adds a Create Monitor UI section + translations.

Changes:

• Add escalation configuration fields (escalateAfterMinutes, escalationNotifications) and a statusChangedAt timestamp to support time-based escalation.
• Add a new notification message type (escalation_alert) and route escalation notifications via NotificationsService.
• Update the Create Monitor form + English locale strings to configure escalation rules.

• NotificationsService now requires a telegramProvider constructor parameter, but the service wiring needs to be updated accordingly (e.g., server/src/config/services.ts currently constructs new NotificationsService(...) without this argument). As-is, this change will break compilation/runtime initialization.
