feat(telemetry): add is_self_hosted tag

[BYK]

Summary

Adds an is_self_hosted boolean tag to Sentry telemetry to distinguish between SaaS and self-hosted instances.

Changes

• Add is_self_hosted tag in initSentry() based on SENTRY_URL configuration
• Consolidate URL utilities in sentry-urls.ts:
  • Move isSentrySaasUrl from region.ts to sentry-urls.ts
  • Use DEFAULT_SENTRY_HOST from constants.ts (removes duplicate)
• Remove getDefaultBaseUrl and isSentrySaasUrl from region.ts

Behavior

SENTRY_URL	is_self_hosted
(default: https://sentry.io)	false
https://us.sentry.io	false
https://sentry.mycompany.com	true
