[roll] Roll fuchsia [power] Stabilize SAG integration test test_no_suspend_loop_files_report

1. Aligning test loop counts with the SAG loop detector threshold to 6
   cycles ensure the detector is properly triggered in all phases.
2. Synchronizing the test with SAG's `suspend_success_count` Inspect
   metric after resume. This ensures SAG has fully processed the resume
   and reset its internal loop detection counters before the test
   cycles leases again.
3. Reducing the test phase timeouts to 55 seconds (shorter than the 60-
   second long wake lease watchdog timeout). This now prevents false-
   positive passes where a failure to trigger the loop detector is
   masked by the watchdog timeout filing a report.
4. Synchronizing initial wake lease satisfaction (`prevent-suspend`)
   before signaling boot completion (`set_boot_complete()`). This can
   prevent a race where the boot lease is dropped before the new wake
   lease is satisfied in the Power Broker, which previously caused the
   system to transition to suspend prematurely and reset the internal
   cycle counter of the loop detector, resulting in a timeout.
