chore: change slack app webhooks (CM-1019)

[themarolt]

Note

Medium Risk
Moderate operational risk: all Slack notifications are rerouted to new CDP_* channels and env var names, so missing/incorrect webhook configuration could silently drop alerts.

Overview
Migrates Slack alerting to a new set of CDP_* webhook channels by replacing the SlackChannel enum values and updating all call sites (API/public API error reporting, cron monitoring jobs, Temporal worker alerts, and Snowflake connector schedules) to use the new channels.

Removes the legacy slackAlerting config/env wiring from backend and workers, and updates the Slack library to read webhook URLs from CDP_*_SLACK_WEBHOOK_URL env vars with clearer missing-config warnings.

Pull request overview

This PR standardizes Slack alerting by renaming/re-scoping Slack channels (and their corresponding webhook environment variables) to a new CDP-prefixed set, while removing the older slackAlerting configuration wiring from multiple services.

Changes:

• Replaced legacy Slack channels (ALERTS, DATA_ALERTS, etc.) with CDP-scoped channels (e.g., CDP_ALERTS, CDP_CRITICAL_ALERTS).
• Updated services to send notifications to the new channels.
• Removed slackAlerting config types + environment variable mappings from backend and workers.
