fix(agents): scope quota failures to auth profiles (#121278)

* fix(agents): scope quota failures to auth profiles

* test: repair provider suspension CI coverage

* test: keep suspension reset fixture internal

* fix(agents): spend cooldown probe only on transient candidates

Consume the one-run cooldown probe only when the candidate’s own unavailable reason is transient, so a billing-disabled pin cannot block a recoverable backup.\n\nFinding from the ClawSweeper review on openclaw/openclaw#121278.

* refactor(sessions): deprecate QuotaSuspension.laneId instead of removing

The shipped plugin-SDK surface deprecation policy requires keeping the inert field until the next surface window.

* fix(agents): extend transient probe policy to plugin-harness auth path

* fix(agents): keep provider overload from cooling auth profiles

* fix(agents): exhaust rotation candidates without cooldown records
