Fix AI energy level platform-flip bug found in Opus review

The switch and select shared a stub-time asymmetry: only the select had a
`not rep` carve-out, so an unfetched-stub rep at the moment platforms are
set up (entity creation runs once, ever) would instantiate a Select, while
flatten() re-evaluates exists_fn every poll against live data -- once the
resource populated to a single-level list, the switch's exists_fn would win
instead and feed the already-created Select a bool through their shared
'ai_energy_level' key, which isn't a valid select option.

Dropped the stub carve-out from the select's exists_fn so both sides
require real, populated data to decide the platform -- on a device that
stubs this cold-tier href on its very first poll, the entity now simply
doesn't appear until a reload, instead of appearing as the wrong widget
type. Added tests for the missing/empty-list supportedAiLevel shapes on
both widgets and a regression test locking in the stub behavior.
