fix(android): Prevent potential crash in checkPowerServiceSaveMode

Darkx-dev · web-flow · commit 811701341be4 · 2025-09-07T01:17:01.000+05:30
The checkPowerServiceSaveMode method used a non-null assertion (!!)
on applicationContext. This could potentially lead to a NullPointerException
in rare edge cases.

This change replaces the assertion with a safe-call block (`?.let`),
ensuring the method safely returns `false` if the context is null,
thereby improving the plugin's robustness.
