## Describe your changes Restore the management gRPC client's backoff reset after a stream connects. This is a regression: PR #4935 originally added this reset; it was then lost in commit `58daa674e` during the `withMgmtStream` refactor (Sync/Job unification). Compared to before the reset was done AFTER receiveEvents, whereas now it's done before. Now should cover for Sync and Job (which didn't exist in #4935. Hold for long living stream that breaks. Reset prevents two things 1. long living conns going wrong from waiting a long backoff time window before to drive reconn 2. past MaxElapsedTime (3months) long lived conns failures from being treated as "unrecoverable" (hence triggering an full restart of the engine) ## Issue ticket number and link Internal support case (customer agents lost data-plane connectivity during a management maintenance/release window). No public issue. Regression introduced in commit `58daa674e`, which removed the `backOff.Reset()` added by PR #4935. ## Stack <!-- branch-stack --> ### Checklist - [x] Is it a bug fix - [ ] Is a typo/documentation fix - [ ] Is a feature enhancement - [ ] It is a refactor - [ ] Created tests that fail without the change (if possible) > By submitting this pull request, you confirm that you have read and agree to the terms of the [Contributor License Agreement](https://github.com/netbirdio/netbird/blob/main/CONTRIBUTOR_LICENSE_AGREEMENT.md). ## Documentation Select exactly one: - [ ] I added/updated documentation for this change - [x] Documentation is **not needed** for this change (explain why) Internal reconnection-behavior fix in the management gRPC client.
