Overflow Tap: the tile says what Tap is on; the corner dot says how it went

The "TAP IS ON · since …" line (and its SWITCHING / NOT SWITCHED forms, and
the red error line under the destination) are gone from the tile. A tile
shows the keyword Tap is on, its destination, the groups moved, the slide
chip and the trail; status is the corner dot's job, as everywhere else in
ProdDash.

The dot now follows the retries honestly: a switch Overflow refuses is
retried three times, ten seconds apart, with the dot amber ("retrying (n of
4 attempts failed)") while the module is still fixing it itself; only when
the attempts are spent does the dot go red with the reason on hover, and the
alert fire if it is switched on. The budget counts refusals in a row across
keywords, not per keyword — a service keeps bringing new keywords, and each
one restarting a fresh budget meant a dead Overflow never turned the dot
red. The alert is raised once per outage, and a success clears the streak.
Verified against the mock with --fail-switch: amber through three refusals,
red on the fourth with one alert, later refusals stay red without
re-alerting, and green again on the first success once the mock is back.
