frontend: fix equipped-card preset auto-selection race

cardsAutoSelectByIccid latched its 'already handled' guard even when no
matching preset was found, so a card equipped before /api/presets had
loaded (the connect-time race with the status/availability polls) never
got auto-selected: navigating to SCP80/RAM showed no preset until the card
was re-inserted.  The guard is now latched only after a successful
selection, and cardsFetch re-runs the auto-selection once the store
arrives, so the card's preset is picked as soon as both resources are
available.

Bumps VERSION to 3.40.3 and the SW cache to simple-v488.
