Clicking the already-active WAR/PEACE button still appended a
\`setDiplomaticStance\` whose \`relation\` matched the row's current
value. The engine would accept the duplicate harmlessly, but the
order tab inflates with rows that say nothing and every auto-sync
re-ships the redundant payload. Compare against the overlayed
stance (so a queued-but-not-applied change suppresses a re-click
that matches the *intended* state, not just the server snapshot)
and short-circuit when they agree. Mirrors the vote picker, which
already had the same guard.
vitest.config.ts: \`mergeConfig\` refuses callback-form base
configs, so resolve \`vite.config.ts\`'s callback with the test
context first and merge the plain object. Surfaced after the
\`loadEnv\` migration switched the root config to the callback
form.
