Wave 11 (M-authexpiry): refresh auth token every sync; recover rows lost to the expired-token sync

Committed by tasks/wave-chain.sh after its mechanical gate passed
(assembleDebug, testDebugUnitTest = 355 tests, verifyPaparazziDebug, no build
files touched, no "always 'false'"). ORCHESTRATOR REVIEW STILL PENDING.
Prompt: tasks/M-authexpiry.txt. Worker: $4.886013000000001, 123 turns.

+A previous worker implemented the task in ~/bookshelf/tasks/M-authexpiry.txt and left the
+working tree FAILING its acceptance gate. Read, in order: ~/bookshelf/docs/SPEC.md,
+~/bookshelf/tasks/M-authexpiry.txt (the original instructions — every constraint in it binds
+you too), ~/bookshelf/logs/M-authexpiry.summary (that worker's report), then the gate output at
+~/bookshelf/logs/gate-M-authexpiry.log. Lines starting "GATE:" and non-zero exits are the failures.
+
+Fix ONLY what makes the gate red. Do not redesign or re-implement the feature. The
+test count must end ABOVE 337 with zero failures; do not delete or @Ignore tests to
+get there. If a Paparazzi verify failed because snapshots were never recorded, record
+them and LOOK at the PNGs before accepting them.
+
+Run in the FOREGROUND (never background a build): ./tasks/gw assembleDebug,
+./tasks/gw testDebugUnitTest, ./tasks/gw verifyPaparazziDebug. Do not git commit/add/push.
+Report what was wrong, what you changed, and the verbatim output tails.
