📄 Description

The previous implementation used a single 10 second backoff for both registration and login operations, default GRPC timeout. However, these are fundamentally different operations with different timeout requirements:

Registration (new peer creation) legitimately needs longer timeouts because it involves database writes, external IdP validation, and group membership calculations. Login (existing peer authentication) is faster and should fail quickly to provide actionable feedback to users.

Describe your changes

This change:

Auto-detects operation type by checking for SetupKey or JwtToken in the request
Uses 180s timeout for registration (5s initial, 30s max interval)
Uses 45s timeout for login (3s initial, 15s max interval)
Extracts backoff creation into helper functions to keep login() complexity low
Maintains backward compatibility - no API changes to public methods

The auto-detection approach eliminates the need for boolean parameters and keeps the login() function simple while providing appropriate timeouts for each scenario.

Summary by CodeRabbit

Bug Fixes
- Improved retry and timeout handling for authentication flows, reducing failed logins and registrations during transient network issues.
- More reliable detection of registration vs. login so each uses an appropriate retry strategy.
- Enhanced error classification to differentiate canceled vs. timed-out requests and avoid unnecessary retries.
- Prevents attempting peer registration when no registration credentials are provided, avoiding needless failures.
Chores
- Internal backoff/retry and logging improvements; no changes to public APIs.
