security: implement comprehensive security audit fixes
Critical Fixes:
- Remove /health/time endpoint exposing system time information
  * Prevents attackers from detecting time sync issues for TOTP attacks
  * Removed route and controller function, updated tests
- Add email confirmation check to account data export
  * GDPR export now requires confirmed email address
  * Prevents unconfirmed accounts from accessing data export
- Add path traversal validation for MIB archive uploads
  * Extract to temp directory, validate all paths, then copy if safe
  * Prevents malicious tar/zip files from writing outside target directory
  * Added validate_extracted_paths/1 helper function

High Priority Fixes:
- Add comprehensive input validation for mobile auth
  * Length limits: device_name (255), device_os (100), app_version (50), push_token (512)
  * Prevents database corruption and storage exhaustion
- Add heartbeat rate limiting to agent channel
  * Limit database updates to once per 30 seconds (max ~2/min per agent)
  * Prevents malicious agents from exhausting database connections
- Sanitize 500 error responses
  * Return generic error messages to clients
  * Log full details server-side with request_id for support
  * Prevents leaking stack traces and module names
- Add message size limits to agent channel
  * 10MB maximum for all protobuf messages (result, heartbeat, error)
  * Prevents DoS attacks via oversized payloads

Medium Priority Fixes:
- Add GraphQL query depth limits (max_depth: 10)
  * Prevents DoS from deeply nested queries
  * Complements existing complexity limits

Code Quality:
- Refactor agent channel handlers to reduce nesting depth
  * Extract message processing into separate private functions
  * Fixes Credo warnings about excessive nesting
  * Improves code readability and maintainability
