fix(crash): Send actual exception string in crash report

This commit modifies the crash reporting mechanism to send the actual exception string as part of the crash report payload.

Previously, the stack trace was read from a log file, which could be unavailable. Now, the `Throwable` exception is converted to a string in `CrashHandler` and passed via an `Intent` extra to `CrashReportActivity`. This ensures the stack trace is reliably included in the JSON payload sent to the remote endpoint, replacing the previous "No stack trace available" placeholder.
