fix: increase e2e test server startup timeout from 10s to 60s

All scripting e2e tests were using 10 second timeout for server startup,
which is insufficient on slower CI runners. Increased to 60 seconds to
prevent flaky test failures.

Also uncommented TestE2E_ScriptingAPI_MatchRules and
TestE2E_ScriptingAPI_Priority which were previously disabled due to
this timeout issue.
