Original Pull Request: https://github.com/netbirdio/netbird/pull/5828

State: closed
Merged: Yes

Describe your changes

Refactor: optimize ICE retry strategy

Refactored isConnectedOnAllWay to return a ConnStatus enum:
- Connected
- Disconnected
- PartiallyConnected
Updated connection handling logic:
- When relay is up but ICE is not (PartiallyConnected):
  - Limit ICE offers to 3 retries with exponential backoff
  - After retries are exhausted, fall back to hourly retry attempts
  - Reduces unnecessary signaling traffic
- When fully disconnected:
  - Continue aggressive retry behavior
Improved resiliency:
- External events (relay/ICE disconnect, signal/relay reconnect) reset retry state
- Ensures ICE gets a fresh retry cycle after state changes
