Fix Issue #586: Migrate errorLogger.ts to validated @/config/env

Summary

Migrated errorLogger.ts from direct process.env reads to the validated @/config/env configuration system, ensuring environment validation fails fast at startup rather than silently degrading at runtime.

Changes

src/utils/errorLogger.ts

• Replaced process.env.NODE_ENV with appConfig.nodeEnv from validated config
• Replaced direct process.env.SENTRY_DSN access with appConfig.sentryDsn
• Added initializeErrorLogger() that runs on module load, logging a clear warning if NEXT_PUBLIC_SENTRY_DSN is not configured
• Prevents silent no-ops by making missing DSN behavior explicit

src/utils/tests/errorLogger.test.ts (new)

• Test: Verifies logger reads from validated config, not process.env directly
• Test: Validates console.warn is called when DSN is missing (no silent failures)
• Test: Confirms initialization succeeds when DSN is present
• Test: Ensures error reporting cannot silently degrade without warning
• Additional tests: Dev/prod logging modes, appConfig.nodeEnv precedence

Why This Matters

• Fail-fast validation: Environment misconfiguration is caught at startup via @/config/env's zod schema, not at runtime
• Visible behavior: Missing Sentry DSN now logs a clear warning instead of silently disabling error reporting
• Consistency: Aligns with project pattern of centralizing environment configuration

Testing

• All tests pass with vitest
• Code follows ESLint rules (no-restricted-syntax satisfied)
• No new dependencies added
• Existing errorLogger API preserved

• Closes errorLogger.ts's direct process.env read — confirm error-logging/reporting doesn't silently no-op in an environment where the expected config path was never validated #586
