Re-enable fee_estimate_query example and remove mirror-sync sleeps

- Remove fee_estimate_query skip block from Taskfile.yml run-examples task
- Remove waitForMirrorNodeSync() calls from sdk/fee_estimate_query_e2e_test.go
- Remove mirrorSyncDelay constant and waitForMirrorNodeSync() helper function
- Rely on waitForFeeEstimationServiceReady() readiness probe instead of arbitrary sleeps

Fixes #1696
